Abstract

The syntheses and crystal structures of a triazolium salt, 4-benzyl-1-ethyl-1,2,4-triazolium bromide, C₁₁H₁₄N₃⁺·Br⁻ (2), and the corresponding N-heterocyclic carbene complexes, (4-benzyl-1-ethyl-1,2,4-triazol-5-yl­idene)chlorido­[(1,2,5,6-η)-cyclo­octa-1,5-diene]rhodium(I), [RhCl(C₈H₁₂)(C₁₁H₁₃N₃)] (3), (4-benzyl-1-ethyl-1,2,4-triazol-5-yl­idene)[(1,2,5,6-η)-cyclo­octa-1,5-diene](tri­phenyl­phosphane)iridium(I) tetra­fluorido­borate, [Ir(C₈H₁₂)(C₁₁H₁₃N₃)(C₁₈H₁₅P)]BF₄ (5), and (4-benzyl-1-ethyl-1,2,4-triazol-5-yl­idene)[(1,2,5,6-η)-cyclo­octa-1,5-diene](tri­cyclo­hexyl­phosphane)iridium(I) tetra­fluorido­borate dicholoro­methane sesquisolvate, [Ir(C₈H₁₂)(C₁₁H₁₃N₃)(C₁₈H₃₃P)]BF₄·1.5CH₂Cl₂ (6), are presented. Complexes 2 and 6 crystallize in the monoclinic space group P2₁/c, complex 3 in the triclinic space group P1 and complex 5 in the triclinic space group P1 with two mol­ecules in the asymmetric unit. The three metal complexes 3, 5, and 6 have a distorted square-planar geometry around the metal ions. The N1—C1—N3 bond angle in the triazolium salt 2 is 107.1 (2)° and is observed in the range of 102.2 (3) to 103.8 (5)° in the NHC ligands in complexes 3, 5, and 6. The two substituent ‘wing tips’ in the NHC ligand (N-ethyl and N-benz­yl) are oriented in an anti-arrangement in compounds 2 and 3, a syn-arrangement in compound 6, and both syn and anti-arrangements in the two independent ion pairs in compound 5. All structures exhibit non-classical hydrogen-bonding inter­actions with the most acidic hydrogen atoms in complexes 2 and 3 playing critical roles in the orientations of structural units.

1. Chemical context

Asymmetric 1,2,4-triazolium cations are of inter­est due to their utility as cations in ionic liquids and as precursors to N-heterocyclic carbenes (NHCs) (Chianese et al., 2004 ▸; Dwivedi et al., 2014 ▸). The crystal structures of several triazolium salts have been reported (Albert et al., 2025 ▸; Maynard et al., 2023 ▸; Kumasaki et al., 2021 ▸, El Bakri et al., 2016 ▸; Guino-o et al., 2015 ▸). NHCs have emerged as universal spectator ligands and as alternatives for phosphanes in transition-metal compounds (Herrmann & Köcher, 1997 ▸; Bourissou et al., 2000 ▸; Weskamp et al., 2000 ▸). They form strong bonds to metal centers (Bortenschlager et al., 2005 ▸) and numerous and ever increasing applications of NHCs as supporting ligands in late-transition-metal catalysis have been reported (Díez-Gonzáles et al., 2009 ▸; Cazin, 2013 ▸; Rovis & Nolan, 2013 ▸). Their catalytic activity in the transfer hydrogenation of unsaturated bonds is of great inter­est and it exemplifies some of the key aspects of green chemistry (Ruff et al., 2016 ▸; Zuo et al., 2014 ▸). Steric and electronic tuning of NHCs is possible by changing the ‘wing tip’ substituents on the nitro­gen atoms (Díez-Gonzáles & Nolan, 2007 ▸; Gusev, 2009 ▸; Mata et al., 2004 ▸). Many imidazole- and triazole-based NHC rhodium and iridium complexes have been synthesized and structurally characterized (Herrmann et al., 2006 ▸; Wang & Lin 1998 ▸; Nichol et al., 2009 ▸, 2010 ▸, 2011 ▸, 2012 ▸; Idrees et al., 2017a ▸,b ▸; Rood et al., 2021 ▸; Rushlow et al., 2021 ▸; Newman et al., 2021 ▸; Castaldi et al., 2021 ▸; Lerch et al., 2024 ▸). Their catalytic activity in the transfer hydrogenation of ketones and imines has also been studied and reported (Hillier et al., 2001 ▸; Albrecht et al., 2002 ▸; Gnanamgari et al., 2007 ▸). In this study we report the syntheses and crystal structures of a new triazolium salt and its corresponding NHC complexes of a neutral rhodium complex and two cationic iridium complexes with different ancillary phosphane ligands.

2. Structural commentary

The triazolium salt (2), C₁₁H₁₄N₃⁺·Br⁻, crystallizes in the monoclinic space group P2₁/c as shown in Fig. 1 ▸. The bond lengths in the triazolium rings indicate aromaticity with C—N bonds exhibiting distances in the range 1.304 (4) to 1.365 (3) Å and an N—N bond distance of 1.379 (3) Å; the N—C—N bond angles in the triazolium ring range from 107.1 (2) to 112.1 (2)°.

The neutral complex (3), Rh(η²,η²-C₈H₁₂)(C₁₁H₁₃N₃)Cl, as illustrated in Fig. 2 ▸, crystallizes in the triclinic space group P. The coordination sphere around the Rh^I ion is formed by the bidentate COD ligand and the monodentate NHC and chloride ligands, resulting in a distorted square-planar geometry. The carbene atom, C1, deviates from the expected sp² hybridization in that the N1—C1—N3 bond angle in the triazole-based carbene is 102.7 (2)°. Other key bond lengths and angle in the structure are: Rh1—C1(NHC) = 2.014 (3) Å, Rh1—Cl1 = 2.3960 (6) Å, and C1—Rh1—Cl1 is 89.14 (7)°.

Compound (5), [Ir(η²,η²-C₈H₁₂)(C₁₁H₁₃N₃)(C₁₈H₁₅P)]⁺·BF₄⁻, comprises a cationic iridium complex and a tetra­fluorido­borate counter-anion, as shown in Fig. 3 ▸. Two cations (A containing Ir1 and B containing Ir1′) and two anions are contained in the asymmetric unit, which crystallizes in the triclinic space group P1. The distorted square-planar geometry around the iridium ion arises from the bidentate (1,2,5,6-η)-cyclo­octa-1,5-diene (COD) ligand, and the monodentate NHC and tri­phenyl­phospane ligands. It is characterized by C1—Ir—P bond angles of 93.14 (17)° for cation A and 94.64 (18)° for cation B. The N—C—N bond angles of the NHC ligand are 103.8 (5) and 102.7 (5)° for cations A and B, respectively. The metal—phospho­rus bond lengths are 2.3302 (15) Å (cation A) and 2.3217 (15) Å (cation B) and the metal—carbene bond lengths are 2.039 (6) Å and 2.029 (6) Å for cations A and B, respectively.

Compound (6), [Ir(η²,η²-C₈H₁₂)(C₁₁H₁₃N₃)(C₁₈H₃₃P)]⁺·BF₄⁻·1.5CH₂Cl₂, comprises a cationic iridium complex, a tetra­fluorido­borate counter-anion, and solvating di­chloro­methane (DCM), Fig. 4 ▸. The complex crystallizes in the monoclinic space group P2₁/c with four formula units in the unit cell. The IrI center of the cationic complex has a distorted square-planar conformation, formed by a cyclo­octa-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a tri­cyclo­hexyl­phosphane ligand. There are several disordered atoms/mol­ecules that were modeled appropriately: one DCM mol­ecule sits on a crystallographic center of symmetry and was modeled with statistical occupancy. Another DCM mol­ecule, COD and BF₄ were modeled for positional disorder. The N1—C1—N3 bond angle in the carbene is 102.2 (3)°. Other selected bond lengths and angle in the structure are Ir1—C1 = 2.034 (4) Å, Ir1—P1 = 2.3707 (9) Å, and C1—Ir1—P1 = 93.42 (10)°.

A comparison of the triazolium salt (2) bond angles and bond lengths to its corresponding NHC ligands in complexes 3, 5,and 6, show significant changes. Key bond lengths and angles for the structures are summarized in Tables 1 ▸–4 ▸ ▸ ▸. The N1—C1—N3 bond angle changes from 107.1 (2)° in 2 to a range of 102.2 (3)° to 103.8 (5)° in complexes 3, 5,and 6. The C1—N1 and C1—N3 bond lengths change from 1.315 (3) and 1.339 (3) Å in compound 2 to a range from 1.336 (8) to 1.352 (5) Å in compounds 3, 5,and 6, and 1.339 (3) to a range of 1.319 (5) and 1.380 (8) Å in compounds 3, 5, and 6 respectively.

In compound (2), the ethyl and the benzyl (wing tip) substituents on the nitro­gen atoms are in an anti-conformation and compound (3) also shows an anti-conformation with respect to the triazolium ring as shown in Figs. 5 ▸ and 6 ▸, respectively. In compound (5), the wing-tip substituents in the carbene ligands are syn in cation A and anti in cation B (Fig. 7 ▸). Fig. 7 ▸ illustrates the different conformations of the two cations. Unlike the tri­phenyl­phosphine analogue (5), in compound (6) only the syn-conformation of the wing tips is observed as shown in Fig. 8 ▸. The different conformations of the wingtips in various structures shows no strong preference for the syn or anti configuration of the wingtips. This is likely due to the ethyl wingtip being relatively small in size.

3. Supra­molecular features

Packing diagrams of the structures are shown in Figs. 9 ▸–12 ▸ ▸ ▸ with non-classical hydrogen-bonding inter­actions shown as red dotted lines and summarized in Tables 5 ▸–8 ▸ ▸ ▸. The triazolium salt (2), shown in Fig. 9 ▸, exhibits close contacts between the two most acidic hydrogen atoms in the structure (H1 and H2 of the triazolium ring) and the bromide anion. The C—H⋯Br⁻ hydrogen bonding inter­actions of 2, summarized in Table 5 ▸, position the bromide ion between adjacent triazolium rings. This behavior is consistent with other observed crystal structures of 1, 2, 4-triazolium halide salts (Guino-o et al., 2015 ▸; El Bakri et al., 2016 ▸; Maynard et al., 2023 ▸; Albert et al., 2024). The neutral rhodium complex (3), shown in Fig. 10 ▸, crystallizes as dimer pairs with the acidic H atom of the NHC (H2) and chlorido ligand on adjacent structural units displaying a weak C—H⋯Cl hydrogen-bonding inter­action, summarized in Table 6 ▸. The ionic iridium complexes (5 and 6), shown in Figs. 11 ▸ and 12 ▸, respectively, display many non-classical hydrogen-bonding inter­actions, summarized in Tables 7 ▸ and 8 ▸, respectively. Most of the close contacts of the cationic complex are directed towards the tetra­fluorido­borate anion in 5. The weak hydrogen bonds in 6 are exhibited between both between adjacent cations and between cations and the tetra­fluorido­borate anion. Potential weak hydrogen-bonding inter­actions between the di­chloro­methane solvate mol­ecule and the cation are all relatively long and are not included in Table 8 ▸. A few short non-standard hydrogen-bonding inter­actions likely occur due to disordered atoms.

4. Database survey

The Crystallography Open Database (Gražulis et al., 2009 ▸) was queried for structures similar to those reported. A search for ‘triazolium’ and ‘salt’ yielded 54 entries in the database. A search for ‘triazol’ that included the element iridium yielded 139 entries. A search for ‘triazol’ that included the element rhodium yielded 83 entries.

5. Synthesis and crystallization

1-Ethyl-1,2,4-triazole (1) was purchased from Matrix Scientific. All other compounds used in the syntheses, detailed in Fig. 13 ▸, were obtained from Sigma–Aldrich and Strem and used as received; all syntheses were performed under a nitro­gen atmosphere. NMR spectra were recorded at room temperature in CDCl₃ on a 400 MHz (operating at 100 MHz for ¹³C and 162 MHz for ³¹P) Varian spectrometer and referenced to the residual solvent peak (δ in p.p.m.). The titular series of compounds (2, 3, 5, and 6) were crystallized by slow diffusion of pentane into a CH₂Cl₂ solution.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 9 ▸. The non-H atoms were refined anisotropically and hydrogen atoms were refined using a riding model. Refinement of 3 and 6 included several disordered atoms/mol­ecules (COD ligand in 3 and COD ligand, tetra­fluorido­borate anion, and di­chloro­methane solvate in 6). In 6, one di­chloro­methane solvate mol­ecule lies on a crystallographic center of symmetry and was modeled using a PART −1 card in SHELXL and as half occupancy.

4-Benzyl-1-ethyl-1,2,4-triazolium bromide (2). Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

(4-Benzyl-1-ethyl-1,2,4-triazol-5-ylidene)chlorido[(1,2,5,6-η)-cycloocta-1,5-diene]rhodium(I) (3). Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
