Crystal structures of three 4-methyl­piperidinium salts (one as three polymorphs) with tetrahalogenidoaurate(III), halide and (in one case) di­chloro­iodate(I) counter-anions

The structures of three 4-methyl­pyridinium tetra­halogenidoaurate(III) halides, one also including a di­chloro­iodate(I) anion, are presented. The crystal packings involve hydrogen, halogen and coinage bonds, and display prominent substructure types involving the cations and halides or the anions alone.

Abstract

The structures of three 4-methyl­pyridinium tetra­halogenidoaurate(III) halides, one also including a di­chloro­iodate(I) anion, are presented. Bis(4-methyl­piperidinium) tetra­bromido­aurate(III) bromide, (4-Me-pipH)₂[AuBr₄]Br, 1, crystallizes in space group C2/c with Z = 4. The gold atom lies on the inversion centre 0.75, 0.75, 0.5 and the bromide ion on the twofold axis 0.5, y, 0.25. Bis(4-methyl­piperidinium) tetra­chlorido­aurate(III) chloride, (4-Me-pipH)₂[AuCl₄]Cl, 2, was obtained as three polymorphs, none of which is isotypic to 1. Polymorph 2a crystallizes in space group P2₁/c with Z = 4; all atoms lie on general positions. Polymorph 2b crystallizes in space group P2/c with Z = 8; two chloride ions lie on the twofold axes 0, y, 1/4 and 0.5, y, 0.25. Polymorph 2c crystallizes in space group P1 with Z = 10; all atoms lie on general positions. Hexa­kis­(4-methyl­piperidinium) tetra­kis­{tetra­chlorido­aurate(III)} di­chloro­iodate(I) chloride, (4-Me-pipH)₆[AuCl₄]₄(ICl₂)Cl, 3, crystallizes in space group P1 with Z = 1; two gold atoms occupy inversion centres, as do the iodine atom and one chloride. This is the first time that we have observed the chlorinating agent PhICl₂ to be ‘non-innocent’. The main inter­est centres on the crystal packings, which involve hydrogen, halogen and coinage bonds, and display prominent substructures, one type involving the cations and the halides, and the other type involving the anions. A common feature in the packing of compounds 1 and 2 is a chain consisting of cations linked by halide ions. In 1, the chains are flanked by tetra­bromido­aurate ions via short Br⋯Br contacts. The anions form zigzag chains via Br⋯Br⁻⋯Br groupings. In polymorph 2a, chains of cations and chloride ions connect to chains of tetra­chlorido­aurate ions to form a layer structure. In polymorph 2b, cation/chloride chains connect with chains of tetra­chlorido­aurate and chloride anions to form a layer structure; approximately linear Au⋯Cl⁻⋯Au groupings are a striking feature (these are also seen in 2c and 3). The asymmetric unit of polymorph 2c is an ensemble ca 27 Å long. Cation/chloride chains are linked by tetra­chlorido­aurates to form one-dimensional polymers. The tetra­chlorido­aurate and chloride ions associate to form a layer structure. In the packing of compound 3 the chloride/tetra­chlorido­aurate substructure is dominant. Two tetra­chlorido­aurate ions associate with the free chloride to form a layer structure; the layers are linked in the third dimension via the third tetra­chloro­aurate and the di­chloro­iodate ions. There is no independent cation/chloride substructure; the cations may be considered as being inter­spersed in the spaces of the anionic substructure, forming hydrogen bonds (some multicentred) to chlorine atoms of the anions. A brief database survey of other structures involving aryl- or alkyl­ammonium cations, tetra­halogenidoaurates and halides is presented, including packing diagrams of selected examples.

1. Chemical context

In this series of publications, we have structurally investigated several classes of amine complexes of gold(I) and gold(III) halides, whereby the term ‘amine’ has been used loosely to include aza­aromatics. The gold(I) derivatives were often synthesized by the reaction of the ligand with chlorido- or bromido­(tetra­hydro­thio­phene)­gold(I), from which the tetra­hydro­thio­phene ligand is easily replaced. Oxidation to the gold(III) species was achieved using elemental bromine or the chlorine equivalent iodo­phenyl dichloride PhICl₂. Extensive background material is given in Part 12 of this series (Döring & Jones, 2023 ▸).

One of the problems in these syntheses is the sensitivity of some products to hydrolysis and to traces of H⁺, so that crystallizations, which often take weeks or months, can lead to salts of the protonated amine with tetra­halogenidoaurates(III). This tendency is exacerbated by the tendency of the frequently used solvent di­chloro­methane to react with amines, even in the absence of any other species (e.g. with pyridine; Rudine et al., 2010 ▸). The structures of the isolated salts have however often proved to be inter­esting in their own right; for instance, they often exhibit short halogen⋯halogen contacts between tetra­halogenidoaurate(III) ions, sometimes leading to networks of these ions (Döring & Jones, 2016 ▸; this publication was not assigned a series number).

In the series of 4-methyl­piperidine (4-Me-pip) complexes, we have previously determined the structures of bis­(4-methyl­piperidine)­gold(I) chloride, [Au(4-Me-pip)₂]Cl; bis­(4-methyl­piperidine)­gold(I) di­chlorido­aurate(I), [Au(4-Me-pip)₂] [AuCl₂]; bis­(4-methyl­piperidine)­gold(I) di­bromido­aurate(I), [Au(4-Me-pip)₂] [AuBr₂]; the 1:1 adduct chlorido­(4-methyl­piperidine)­gold(I) bis­(4-methyl­piperidine)­gold(I) chlor­ide, AuCl(4-Me-pip)·[Au(4-Me-pip)₂]Cl, as its di­chloro­methane solvate (Döring & Jones, 2024a ▸); tri­chlorido­(4-Me-pip)gold(III), (4-Me-pip)AuCl₃; tri­bromido­(4-Me-pip)gold(III), (4-Me-pip)AuBr₃ (Döring & Jones, 2024b ▸); and 4-methyl­piperidinium tetra­chlorido­aurate(III), (4-Me-pipH)[AuCl₄] (Döring & Jones, 2016 ▸). In the last of these papers, we presented the structures of six compounds for which the tetra­halogenidoaurate ions assembled to form approximately square networks with gold atoms at the corners and short halogen⋯halogen contacts Au—X⋯X—Au along the sides of the squares (Fig. 1 ▸). Here we present the structures of the more complex ionic systems bis­(4-methyl­piperidinium) tetra­bromido­aurate(III) bromide, (4-Me-pipH)₂[AuBr₄]Br 1; bis­(4-methyl­piperidinium) tetra­chlorido­aurate(III) chloride, (4-Me-pipH)₂[AuCl₄]Cl 2 (three polymorphs); and hexa­kis­(4-methyl­piperidinium) tetra­kis­{tetra­chlorido­aurate(III)} di­chloro­iodate(I) chloride, (4-Me-pipH)₆[AuCl₄]₄(ICl₂)Cl 3. The presence of both halide and tetra­halogenidoaurate ions extends the potential types of anion assemblies.

2. Structural commentary

All compounds crystallize solvent-free. In the Figures (Figs. 2 ▸–6 ▸ ▸ ▸ ▸), the asymmetric units have been extended by symmetry where necessary to show complete residues; the dashed lines indicate short contacts that are discussed in Supra­molecular features. Bis(4-methyl­piperidinium) tetra­bromido­aurate(III) bromide, (4-Me-pipH)₂[AuBr₄]Br 1 (Fig. 2 ▸) crystallizes in space group C2/c with Z = 4. The gold atom lies on the inversion centre 0.75, 0.75, 0.5 and the bromide ion on the twofold axis 0.5, y, 0.25. Bis(4-methyl­piperidinium) tetra­chlorido­aurate(III) chloride, (4-Me-pipH)₂[AuCl₄]Cl 2, was obtained as three polymorphs, none of which is isotypic to 1. Polymorph 2a (Fig. 3 ▸) crystallizes in space group P2₁/c with Z = 4; all atoms lie on general positions. Polymorph 2b (Fig. 4 ▸) crystallizes in space group P2/c with Z = 8; two chloride ions lie on the twofold axes 0, y, 0.25 (Cl10) and 0.5, y, 0.25 (Cl11). Polymorph 2c (Fig. 5 ▸) crystallizes in space group P with Z = 10; all atoms lie on general positions. The asymmetric unit thus contains 20 residues. The chlorine atoms of the tetra­chlorido­aurate anions are numbered Cl1–Cl20 and the free chloride ions Cl21–Cl25. Hexa­kis­(4-methyl­piperidinium) tetra­kis­{tetra­chlorido­aurate(III)} di­chloro­iodate(I) chloride, (4-Me-pipH)₆[AuCl₄]₄(ICl₂)Cl 3 (Fig. 6 ▸) crystallizes in space group P with Z = 1; two gold atoms occupy inversion centres, Au2 at 1, 0.5, 0.5 and Au3 at 0.5, 0, 0, as do the iodine atom I1, at 1, 1, 0.5, and one chloride, Cl9, at 0.5, 0.5, 0. This is the first time in our experience that the chlorinating agent PhICl₂ has proved to be ‘non-innocent’.

Selected mol­ecular dimensions are shown in Tables 1 ▸–5 ▸ ▸ ▸ ▸. The tetra­halogenidoaurate(III) ions show the expected square-planar (4/mmm) symmetry to a good approximation, although there is some scatter of the Au—Cl bond lengths, which range from 2.2624 (13) to 2.3007 (8) Å. It is tempting to suggest that the differences are attributable to the short inter­ionic contacts, but no clear pattern can be discerned. In the cations, the methyl substituent is consistently equatorial, with C—C—C—C_meth­yl torsion angles around ±180°.

3. Supra­molecular features

In the packing diagrams, atom labels indicate atoms of the asymmetric unit (except where otherwise indicated). Hydrogen atoms of CH₂ and CH groups are omitted (but their contacts are present in the deposited material); we subjectively assess the C—H⋯X contacts to be less important than N—H⋯X, although there are several of the former type, as would be expected in compounds with many more C—H than N—H moieties. In the text, primes (′) indicate previously defined or generalized symmetry operators. Classical hydrogen bonds are listed in Tables 6 ▸–10 ▸ ▸ ▸ ▸.

A common feature in the packing of compounds 1 and 2 is a chain consisting of cations linked by halide ions. The closely related compounds (pipH)₂[AuCl₄]Cl and (pyrrolidinium)₂[AuBr₄]Br (Döring & Jones, 2023 ▸) both show related chains; the latter was shown in the original publication, but the former was not shown explicitly, so we provide it here (Fig. 7 ▸). The chains involve hydrogen-bonded rings, each with two cationic NH₂ groups and two chloride ions, with graph set (8). These are connected by the apical chloride anions, which accept four hydrogen bonds, two from each of the two connected rings. The presence of an alkyl­ammonium-type cation is not a prerequisite for such chains; another example is the structure of bis­(cyclo­hexyl­amine)­gold(I) chloride (Döring & Jones, 2018 ▸), which has a formally uncharged NH₂ group in the coordinated amine. The packing of compound 1 involves exactly analogous chains of NH₂ groups and bromides, running parallel to the c axis (Fig. 8 ▸); each chain is flanked by tetra­bromido­aurate ions via short contacts Br3⋯Br1 of 3.6584 (7) Å, which can be classified as halogen bonds (for reviews see e.g. Metrangelo et al., 2008 ▸ or Cavallo et al., 2016 ▸). Fig. 9 ▸ shows the zigzag chains formed by the anions; the angle Br1⋯Br3⋯Br1(1 − x, y,  − z) is 74.38 (2)° and Au1—Br1⋯Br3′ is 168.10 (2)°. The chains propagate parallel to [101]. Fig. 10 ▸ shows a projection of the complete packing parallel to the c axis; the cation/bromide chains occupy the regions at the corners and the centre of the projected cell.

In compound 2, polymorph 2a, chains of cations and chloride ions run parallel to the b axis, but the arrangement differs from that of compound 1 in that the apically linked rings are of two alternating types. One type, involving N11 and its hydrogens, is the same graph set (8) as for 1, but the other rings only involve one hydrogen H04 at N21, thus forming H₂Cl₂ rings of graph set (4) (Fig. 11 ▸). The other hydrogen H03 forms a long hydrogen bond to Cl3 of the tetra­chlorido­aurate ion. A further type of chain, which also runs parallel to the b axis, is formed of tetra­chlorido­aurate ions only, with short axial Cl3⋯Au1( − x, − + y,  − z) contacts of 3.5574 (8) Å and an Au1—Cl3⋯Au1′ angle of 160.69 (3)° (Fig. 12 ▸). Such contacts are well-known for square-planar gold(III) species and have recently been formalized as ‘coinage bonds’ (Daolio et al., 2021 ▸; Pizzi et al., 2022 ▸). The chains are linked by the H03⋯Cl3 hydrogen bond and by a short Cl4⋯Cl5 contact of 3.6319 (11) Å. The two types of chain are linked to form a layer structure parallel to (10) (Fig. 13 ▸, in which the chains run horizontally).

In polymorph 2b, the cation/chloride chains again consist solely of apex-linked (8) rings, which run parallel to the a axis (Fig. 14 ▸). The tetra­chlorido­aurate and chloride anions Cl9 associate to form zigzag chains with overall direction parallel to the b axis (Fig. 15 ▸), with short contacts Au1⋯Cl9 = 3.3908 (12), Au2⋯Cl9 = 3.7034 (12) and Cl2⋯Cl6(x, −1 + y, z) = 3.4761 (17) Å. Associated angles are Au1⋯Cl9⋯Au2 = 174.97 (4), Au1—Cl2⋯Cl6′ = 154.66 (5) and Au2—Cl6⋯Cl2(x, 1 + y, z) = 163.48 (5)°, whereby the approximately linear Au⋯Cl⁻⋯Au grouping at the chloride ion Cl9 is striking. The anion chains of the polymorphs 2a, with propagation via axial Au⋯Cl contacts only, and 2b, with Au⋯Cl⁻⋯Au and Cl⋯Cl contacts, are thus quite different. The two chain types of 2b combine to form a layer structure parallel to the ab plane (Fig. 16 ▸). The inter-chain linkages, in which Cl9 plays a prominent part (it accepts four hydrogen bonds and two coinage bonds), include the three-centre hydrogen bond systems N11—H02⋯(Cl4, Cl9) and N41—H41B⋯(Cl4, Cl9). The second disorder component of the ring at N41, which is not shown in the Figures, forms hydrogen bonds to Cl10 (short) and Cl9 (long).

The asymmetric unit of polymorph 2c (Fig. 5 ▸), an ensemble of 20 residues approximately 27 Å long, was chosen to contain a chain of four complete (8) rings, linked at the apices Cl22, Cl23 and Cl24. At the right-hand end of this ensemble, the donor N101—H019 is part of a three-centre hydrogen bond to Cl5 and Cl8, two chlorines of the tetra­chlorido­aurate anion centred on Au2. At the left-hand end, the donor N11—H02 seems at first sight to be unused, but it is linked to Cl6 of the same tetra­chlorido­aurate ion, translated by the operator (1 + x, y, −1 + z). This leads to the formation of a one-dimensional polymer parallel to [10] (Fig. 17 ▸). The tetra­chlorido­aurate/chloride substructure is given first as a simplified view (Fig. 18 ▸), in which the inter­actions (Table 11 ▸) are of the type Au⋯Cl⁻ (via coinage bonds to the free chlorides) or Cl⋯Cl (between tetra­chlorido­aurate ions). Two separate regions based on Au1–3 and Au4/5 can be recognised, each of which contains an Au⋯Cl⁻⋯Au grouping, both forming one-dimensional arrays parallel to the b axis. This view, however, omits the contacts Au1⋯Cl19 and Au2⋯Cl14 between the tetra­chlorido­aurate ions of the two arrays. The view including these contacts (Fig. 19 ▸) is much more complex. It shows the formation of a layer parallel to (02). The contact lengths have been inter­preted liberally as regards length; one of the former is very long, whereas some of the latter are extremely short. The cation/chloride assemblies of Fig. 17 ▸ inter­sect with the tetra­chlorido­aurate substructure via the hydrogen and coinage bonds at Cl22, the hydrogen bonds H02⋯Cl6′ and H019⋯(Cl5, Cl8) and possibly the borderline contact Cl20⋯Cl21. A projection of the entire structure down the b axis (Fig. 20 ▸) shows the tetra­chlorido­aurate/chloride layers edge-on, running diagonally.

The packing of compound 3 also involves hydrogen bonds and a chloride/tetra­chlorido­aurate substructure. It is more convenient to begin with the latter, for which Au⋯Cl and Cl⋯Cl contacts are listed in Table 12 ▸. The tetra­chlorido­aurate ions centred on Au1 and Au2 associate with the free chloride Cl9 to form a layer structure parallel to the ac plane (Fig. 21 ▸), whereby Cl9 again features as part of a linear Au1⋯Cl9⋯Au1′ grouping, cross-linking the chains of tetra­chlorido­aurate ions running parallel to [102]. It is noteworthy that Cl8 participates in two Cl⋯Cl contacts, so that the angles Au1—Cl2⋯Cl(8,10′) are less linear. A projection parallel to the a axis (Fig. 22 ▸) shows how the layers are linked via the third tetra­chloro­aurate and the di­chloro­iodate ions.

In contrast to the other structures, compound 3 does not form an essentially independent cation/chloride substructure. Instead, the cations may be considered as inter­spersed in the spaces of the anionic substructure, forming hydrogen bonds to chlorine atoms of the anions (Fig. 23 ▸). The hydrogen atoms at N21 are involved in a four-centre and a three-centre hydrogen bonding system, H03⋯(Cl3, Cl5, Cl6′) and H04⋯(Cl2, Cl10); several of the H⋯Cl distances (not only these) are quite long. The free chloride Cl9 accepts four hydrogen bonds and two coinage bonds.

4. Database survey

This survey reports on the extent and types of inter­action between the anions of structures involving both halide and tetra­halogenidoaurate(III) ions; these can in principle involve any of the following contact types: Au—X⋯X—Au; Au—X⋯X⁻; Au⋯X—Au and Au⋯X⁻. The search employed the routine ConQuest (Bruno et al., 2002 ▸), part of Version 2024.3.0 of the CSD (Groom et al., 2016 ▸). A search for structures containing an NH⁺ function, an [AuX₄]⁻ and an X⁻ ion was carried out; it was restricted to non-disordered and error-free structures. Our own previously published structures were excluded, whereafter 24 hits remained. The mere presence of both ion types in a structure is no guarantee of a substructure involving the anions; thus tris­(iso­propyl­ammonium) bis­(tetra­chlorido­aurate(III)) dichloride (refcode DIWYOA; Döring & Jones, 2018 ▸) involves no Cl⋯Cl or Au⋯Cl contacts. One would intuitively expect that the larger the cations, the less chance the anions have to approach each other closely enough to form substructures. Indeed, few of the 24 structures display an anionic framework in more than one dimension. Typical 1D-substructures, axially linked chains of the form ⋯Au⋯Cl⁻⋯Au⋯Cl⁻⋯ with Au⋯Cl = 3.670 or 3.640 Å and linear geometry at the bridging chloride, are seen in 1,2-bis­(4-pyridinium)ethane tetra­chlorido­aurate(III) chloride and the isotypic trans-1,2-bis­(4-pyridinium)ethene derivative (CITKIA & CITKOG, Bourne & Moitsheki, 2008 ▸). 4,4′-bipyridinium tetra­chlorido­aurate(III) chloride, with Au⋯Cl 3.683 Å, is similar (NENNIE, Zhang et al., 2006 ▸). In the following, we discuss some of these structures in more detail, giving additional Figures for those structures where the packing was not presented, or in some cases alternative views to those published. At the outset it should be stressed that classical hydrogen bonds, in which the free halide ions often participate, are ignored in this discussion.

In 4,4′-bis­(1H-pyrazol-2-ium) tetra­chlorido­aurate(III) chloride (GAZSEH; Domasevitch, 2012 ▸), the tetra­chlorido­aurate ions display the well-known ‘offset stacking’ or ‘ladder’ pattern, whereby one Au—Cl bond of each ion lies anti­parallel to an Au—Cl bond of each stack neighbour, thus enabling two Au⋯Cl coinage bonds to be formed between pairs of ions. This type of substructure has often been reported in neutral trihalogenidogold(III) species such as the four modifications of (tetra­hydro­thio­phene)AuCl₃ (Upmann et al., 2017 ▸). The same pattern was reported for the tetra­bromido­aurate ions of p-phenyl­enedi­ammonium tetra­bromido­aurate(III) bromide (GEVHAR; Rajeswaran et al., 2007 ▸), but a closer inspection shows that the bromide ion also forms Br⋯Br contacts, leading to a three-dimensional packing, a section of which is shown in Fig. 24 ▸. In bis­(ethane-1,2-di­ammonium) tetra­chlorido­aurate(III) trichloride (KIKYOU; Makotchenko et al., 2013 ▸), layers of anions are formed that involve two axial inter­actions in an Au⋯Cl⁻⋯Au grouping (distances of 3.190 and 3.230 Å) and a very short Cl⋯Cl contact of 3.045 Å between tetra­chlorido­aurate ions, leading to an approximately square network. In bis­(di­ethyl­enetri­ammonium) tris­[tetra­bromido­aurate(III)] tribromide (UYOLAX; Makotchenko et al., 2014 ▸), layers consisting solely of tetra­bromido­aurate ions (Fig. 25 ▸) are formed, which contain pairs of offset-stacked ions involving Au1. These are linked in the third dimension by an inversion-symmetric Au—Br⋯Br⁻⋯Br—Au grouping. The second free bromide is attached terminally to the layer, but these contacts are not shown here. The packing was discussed (and contact distances given) in the original paper, but we present it here in a slightly different way. For the structure of 6-amino-7H-purine-1,9-diium tetra­choridoaurate(III) chloride hydrate (ZUKTEH; Savchenkov et al., 2020 ▸), the anion substructure was presented without contacts being explicitly drawn, and the contact distances were not complete. Fig. 26 ▸ shows linear chains of residues parallel to the a axis in the region z ≃ 0.75; further chains occupy the region z ≃ 0.25. The layer involves five short contacts: Au1⋯Cl5(− + x,  − y, z) = 3.284, Au1⋯Cl10(1 − x, −y,  + z) =3.438, Au2⋯Cl1 = 3.507, Au2⋯Cl3( + x,  − y, z) = 3.315, and Cl7⋯Cl9( − x,  + y, − + z) = 3.627 Å. The asymmetric unit forms an offset-stacked pair of tetra­chlorido­aurate ions. The layers are joined parallel to the c axis by the contact Cl2⋯Cl4(1 − x, −y,  + z) 3.635 Å. The free chloride ions Cl9 and Cl10 are terminally linked to the chains (i.e. they have no bridging function to other anions, although they play an important role in the hydrogen bonding). The compound bis­(cyclo­hexyl­ammonium) tetra­bromido­aurate(III) bromide is reported in a CSD Communication (ZUYLEM; Stender et al., 2016 ▸). The tetra­bromido­aurate ions assemble via the contacts Au1⋯Br3(x,  + y,  − z) = 3.873 and Br1⋯Br1(1 − x, 1 − y, −z) = 3.431 Å to form layers parallel to the bc plane at x = 0, 0.5, 1, etc. (Fig. 27 ▸); layers are linked in the third dimension by the free bromide Br4, with Br2⋯Br4( + x,  + y, z) = 3.787 Å.

Further Br4⋯Br2 and Br4⋯Br3 contacts (3.588 and 3.818 Å respectively) connect the ‘ladder’ substructures, extending the structure in the view direction.

5. Synthesis and crystallization

More details are given in the PhD thesis of CD (Döring, 2016 ▸). Red needles of 1 were obtained from attempts to synthesize (4-Me-pip)AuBr₃ by the oxidation of [(4-Me-pip)₂Au][AuBr₂] with bromine; the solvent system was di­chloro­methane/diisopropyl ether. Similar attempts to obtain (4-Me-pip)AuCl₃ by the oxidation of [(4-Me-pip)₂Au][AuCl₂] with PhICl₂ in various solvent systems led to (4-Me-pipH)[AuCl₄] (Döring & Jones, 2016 ▸) and 2a (yellow plates) as a crystalline mixture from di­chloro­methane/diisopropyl ether; 2c (irregular orange blocks) from di­chloro­methane/diethyl ether; and 2b (yellow plates) from aceto­nitrile using a twofold excess of PhICl₂ (by evaporation). Other solvent systems, in combination with stoichiometric or excess PhICl₂, led either to 2c alone or to mixtures of these polymorphs. Finally, 3 (orange plates) was obtained by recrystallizing a sample of ‘(4-Me-pip)AuCl₃’ from a mixture of nitro­methane and pentane. Clearly a small amount of PhICl₂ took part at some stage in a reaction other than simple chlorination of the gold(I) species. This was our only observation of this behaviour across a wide range of chlorination reactions.

6. Refinement

Computer programs: CrysAlis PRO (Rigaku OD, 2013 ▸), SHELXS97 (Sheldrick, 2008 ▸), SHELXL2019/3 (Sheldrick, 2015 ▸), XP (Bruker, 1998 ▸) and publCIF (Westrip, 2010 ▸).

Structures were refined anisotropically on F². Most hydrogen atoms of the NH₂ groups were refined freely but with N—H distances restrained to be approximately equal (command ‘SADI’; for exceptions, see below). Methyl­ene and methine hydrogens were included at calculated positions and refined using a riding model with C—H = 0.99 or 1.00 Å, respectively. Methyl groups were included as idealized rigid groups with C—H = 0.98 Å and H—C—H = 109.5°, and were allowed to rotate but not tip (command ‘AFIX 137’). U values of the hydrogen atoms were fixed at 1.5 × U_eq of the parent carbon atoms for methyl groups and 1.2 × U_eq of the parent carbon atoms for other hydrogens. A small number of badly fitting reflections were omitted (2c, eight reflections with deviations > 7σ; 3, three reflections > 7σ).

Special features and exceptions: For 2c and 3, H⋯H distances across the NH₂ groups were also restrained with SADI. For 2c, the hydrogen atoms at N6, N7 and N8 were located in difference maps but could not be refined freely, they were therefore placed at calculated positions (N—H = 0.91 Å) and refined using a riding model. For 2b, the cation at N4 is disordered over two positions with occupancies 0.538 (7) and 0.462 (7) Å. The two positions were refined isotropically, with hydrogen atoms of the NH₂ groups included using a riding model (with N—H = 0.91 Å). Appropriate restraints were employed to improve refinement stability, but the dimensions of disordered groups should always be inter­preted with caution.
