Crystal structures of {1,1,1-tris­[(salicylaldimino)­meth­yl]ethane}­gallium as both a pyridine solvate and an aceto­nitrile 0.75-solvate and {1,1,1-tris[(salicylaldimino)­meth­yl]ethane}­indium di­chloro­methane solvate

The crystal structures of gallium and indium coordinated by the sexadentate ligand 1,1,1-tris­[(salicyl­idene­amino)­meth­yl]ethane are presented as different solvates. The syntheses, melting points, infra-red (IR) spectra, high-resolution mass spectra, and ¹H and ¹³ NMR spectra are also reported.

Abstract

The sexa­dentate ligand 1,1,1-tris­[(salicyl­idene­amino)­meth­yl]ethane has been reported numerous times in its triply deprotonated form coordinated to transition metals and lanthanides, yet it has been rarely employed with main-group elements, including in substituted forms. Its structures with gallium and indium are reported as solvates, namely, ({[(2,2-bis­{[(2-oxido­benzyl­idene)amino-κ² N,O]meth­yl}prop­yl)imino]­meth­yl}phenololato-κ² N,O)gallium(III) pyridine monosolvate, [Ga(C₂₆H₂₄N₃O3)]·C₅H₅N, the aceto­nitrile 0.75-solvate, [Ga(C₂₆H₂₄N₃O₃)]·0.75C₂H₃N, and ({[(2,2-bis­{[(2-oxido­benzyl­idene)amino-κ² N,O]meth­yl}prop­yl)imino]­meth­yl}phenololato-κ² N,O)indium(III) di­chloro­methane monosolvate, [In(C₂₆H₂₄N₃O₃)]·CH₂Cl₂. All three metal complexes are pseudo-octa­hedral and each structure contains multiple weak C—H⋯O and/or C—H⋯N inter­molecular hydrogen-bonding inter­actions. The syntheses and additional characterization in the forms of melting points, high-resolution mass spectra, infra-red (IR) spectra, and ¹H and ¹³C NMR spectra are also reported.

Chemical context  

The synthesis of the sexadentate ligand, 1,1,1-tris­[(salicyl­idene­amino)­meth­yl]ethane, H₃(sal)₃tame (Fig. 1 ▸) was first reported nearly fifty years ago (Johnston, 1974 ▸), although its structure was published recently (Yamaguchi et al., 2008b ▸). Complexes of the triply deprotonated ligand, (sal)₃tame, have been reported with transition metals and lanthanides (Sunatsuki et al., 2008 ▸; Yamaguchi et al., 2004 ▸, 2008a ▸,b ▸; Yokoyama et al., 2010 ▸; Kojima, 2000 ▸; Kobayashi et al., 2006 ▸; Urushigawa et al., 1977 ▸), but have received little attention to date with main-group elements (Katsuta et al., 2012 ▸; Kojima et al., 2000 ▸). The H₃(sal)₃tame ligand has already been used to synthesize potential technetium radiopharmaceuticals (Marmion et al., 1996 ▸). There has also been inter­est in polydentate ligands in indium and gallium complexes to be used in radiopharmaceuticals, positron emission tomography, and fluorescence imaging (Liu et al., 1993a ▸,b ▸; Green et al., 1984 ▸; Liu et al., 1992 ▸; Moerlein & Welch, 1981 ▸; Evans & Jakubovic, 1988 ▸; Zhang et al., 1992 ▸; Gut & Holland, 2019 ▸; Arrowsmith et al., 2011 ▸). Herein we report of the syntheses of the title compounds in good yields along with their respective crystal structures.

Structural commentary  

The asymmetric unit of 1a (Fig. 2 ▸) contains the gallium center, the (sal)₃tame ligand, and one co-crystallized pyridine solvent mol­ecule, all in general positions. The geometry is pseudo-octa­hedral, with the smaller angles ranging from 82.13 (6) to 95.97 (6)° (Table 1 ▸). The average Ga—N and Ga–O bond lengths are 2.071 (3) and 1.924 (2) Å, respectively, similar to those found in the the structure of the analogous Ga mol­ecule with a (sal)₃tame-O-iso-Bu ligand [2.080 (5) and 1.916 (3) Å; Green et al., 1993 ▸]. The asymmetric unit of 1b (Fig. 3 ▸) contains two independent [(sal)₃tame]gallium complexes and one co-crystallized aceto­nitrile solvent mol­ecule in general positions and one-half of a co-crystallized acetonitile solvent mol­ecule on a crystallographic inversion center. Analogous bond lengths and angles of the two metal complexes of 1b are nearly identical with each other (Table 2 ▸) and to those of 1a. The geometry is also pseudo-octa­hedral with the smaller angles ranging from 82.74 (6) to 95.36 (6)° and 82.12 (7) to 97.10 (6)° for the two mol­ecules. The indium analog 2 (Fig. 4 ▸) has the metal center, one (sal)₃tame ligand, and one co-crystallized di­chloro­methane solvent mol­ecule in general positions in its asymmetric unit. The geometry is more distorted from octa­hedral (Table 3 ▸) than found in mol­ecules 1a and 1b with angles ranging from 82.19 (5) to 105.02 (5)°, but consistent with those found in known mol­ecules of indium with (sal)₃tame ligands that are substituted at the second ethane carbon atom (Gottschaldt et al., 2009 ▸), likely due to the larger effective ionic radius of six-coordinate indium(III) (0.94 Å) versus gallium(III) (0.76 Å; Shannon, 1976 ▸).

Supra­molecular features  

All three structures have multiple weak C—H⋯O and/or C—H⋯N hydrogen bonds. These are listed in Tables 4 ▸–6 ▸ ▸, respectively, for the three structures. The ring systems were also examined for possible π–π inter­actions. In 1a, the phenyl ring C21–C26 is adjacent to the pyridine solvent mol­ecule, with atom C24 being at a distance of 3.429 (3) Å from the pyridine ring plane; however, the angle between their planes of 26.09 (9)° directs the π orbitals away from the other ring. There is a partial overlap of parallel rings in 1b. Atoms C24 and C25 overlap their inversion-symmetry equivalents (1 − x, −y, −z) at a plane–plane distance of approximately 3.3 Å (Fig. 5 ▸).

Database survey  

There are two instances of the unsubstituted (sal)₃tame ligand coordinated to a single metal center in a sexadentate manner found in the Cambridge Structural Database (CSD, Version 5.41, November 2019 update; Groom et al., 2016 ▸). One is a manganese cation (refcode YUKCOW; Drew et al., 1995 ▸) and the other is a neutral iron complex (refcode NOZJER; Deeney et al., 1998 ▸). If substitution is allowed at the second carbon of the ethane moiety, there are six additional structures, two of which contain the main-group elements Ga and In as mentioned above (see Structural commentary). If substitution is allowed on the phenyl rings, ten additional structures are found, including one with Ga (refcode CIWXIP; Green et al., 1984 ▸). With bridging allowed at the oxygen sites, 24 additional multimetallic structures are found, but none are with main-group metals.

Synthesis and crystallization  

The H₃(sal)₃tame ligand was synthesized via literature procedures [Liu et al., 1993a ▸; Kojima et al., 2000 ▸; Robards & Patsalides, 1999 ▸; Marmion et al., 1996 ▸ (¹H NMR spectra); Ohta et al., 2001 ▸].

[(Sal)₃tame]gallium(III), 1. 0.050 g of H₃(sal)₃tame ligand (0.12 mmol) were stirred in 10 mL of methanol under an N₂(g) atmosphere. 0.030 g of gallium(III) nitrate hydrate (0.12 mmol) in 10 mL of degassed methanol was added dropwise to the ligand solution along with 0.5 mL of tri­ethyl­amine. This was stirred at room temperature under N₂ for 45 minutes. The white solid was filtered and washed with water and methanol. Yield: 0.034 g (61%). M.p. 613–618 K (dec.). IR (neat), ν (cm⁻¹): 2907, 1643, 1621, 1598, 1536, 1468, 1445, 1394, 1336, 1308, 1198, 1146, 1024, 893, 761. ¹H NMR (400 MHz, DMSO-d ₆, δ, ppm): 1.09 (s, 3H), 3.46 (d, 3H, J = 14.0 Hz), 4.06 (d, 3H, J = 13.6 Hz), 6.47 (d, 3H, J = 8.0 Hz), 6.55 (t, 3H, J = 7.6 Hz), 7.15–7.23 (m, 6H), 8.29 (s, 3H). ¹³C NMR (100 MHz, DMSO-d ₆, δ, ppm): 23.1, 34.9, 65.8, 114.6, 119.2, 122.3, 134.4, 134.6, 168.7, 169.9. Calculated for C₂₆H₂₄N₃O₃GaNa: 518.10. Found: 518.10. The solid material was dissolved in pyridine (1a) or aceto­nitrile (1b), and hexa­nes were diffused into the solution to give light-yellow single crystalline blocks.

[(Sal)₃tame]indium(III), 2. 0.037 g of H₃(sal)₃tame ligand (0.09 mmol) were stirred in 10 mL of methanol under an N₂(g) atmosphere. 0.019 g of indium chloride (0.09 mmol) in 10 mL of degassed methanol was added dropwise to the ligand solution along with 0.5 mL of tri­ethyl­amine. This was stirred at room temperature under N₂ for 45 minutes and allowed to sit overnight. The light-yellow solid was filtered and washed with water and methanol. Yield: 0.0322 g (69%). M.p. 658–663 K. IR (neat), ν (cm⁻¹): 2914, 1617, 1537, 1465, 1441, 1398, 1347, 1306, 1191, 1019, 893, 761. ¹H NMR (400 MHz, DMSO-d ₆, δ, ppm): 1.09 (s, 3H), 3.83 (s, 6H), 6.56 (t, 3H, J = 8.0 Hz), 6.62 (d, 3H, J = 10.5 Hz), 7.19–7.23 (m, 6H), 8.37 (s, 3H). ¹³C NMR (100 MHz, DMSO-d ₆, δ, ppm): 24.5, 36.6, 67.4, 114.8, 119.1, 123.1, 134.5, 135.9, 170.6, 173.3. Calculated for C₂₆H₂₄N₃O₃InNa: 564.07. Found: 564.08. The solid material was dissolved in di­chloro­methane, and hexa­nes were diffused into the solution to give colorless single crystalline blocks.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 7 ▸. Aceto­nitrile mol­ecule N8–C55–C56 in 1b was modeled as disordered over a crystallographic inversion center (0.50:0.50). Analogous bond lengths of the disordered solvent mol­ecule were restrained to be similar to those of the ordered solvent mol­ecule (N7–C53–C54). Anisotropic displacement parameters were heavily restrained toward the expected, realistic thermal motion of each atom along the solvent mol­ecule (SHELXL hard restraint ‘RIGU’; Thorn et al., 2012 ▸).

({[(2,2-Bis{[(2-oxidobenzylidene)amino-κ²N,O]methyl}propyl)imino]methyl}phenololato-κ²N,O)gallium(III) pyridine monosolvate (1a) . 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.

Refinement. One cocrystallized acetonitrile solvent molecule is modeled as disordered over a crystallographic inversion center (50:50). Analogous bond lengths of the disordered solvent molecule were restrained to be similar to those of the ordered solvent molecule. Anisotropic displacement parameters were restrained toward the expected thermal motion of each atom along the solvent molecule.

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.
