Crystal structure of chlorido-[diphen-yl(thio-phen-2-yl)phosphine-κP]gold(I).

The crystal structure of the title compound, [AuCl(C16H13PS)], is reported. The mol-ecular structure features a nearly linear arrangement of the chloride and phosphino ligands around the gold(I) center, with a P-Au-Cl bond angle of 179.42 (9)°. The Au-P and Au-Cl bond lengths are 2.226 (2) and 2.287 (2) Å, respectively. The geometry of the groups bonded to the phospho-rus atom of the ligand is a slightly distorted tetra-hedron. The phenyl and thienyl rings of the ligand are extensively disordered, with the thienyl refined over all three possible positions on the phospho-rus atom. The relative occupancy ratio between these positions was found to be 0.406 (3):0.406 (2):0.188 (2). One of the major thienyl ring positions with the relative occupancy of 0.406 was modeled as two rotational isomers around the C-P bond with a relative occupancy ratio of 0.278 (3):0.128 (3). Inter-molecular C-H⋯π inter-actions present in the crystal lattice link mol-ecules of the title compound together to form a complex three-dimensional network. © Neils et al. 2022.

Chemical context

The incorporation of tri­aryl­phosphines as ligands in metal complexes has led to a multitude of species capable of, for example, catalyzing organic transformations, binding to biological targets, and combating cancer. The synthesis of unsymmetric tri­aryl­phosphines has the potential to add additional functionality and selectivity to the resultant metal–ligand complexes. If we consider gold(I)–PAr3 complexes, structural diversity of the phosphine ligand has led to properties such as selective catalysis for cyclo­isomerization reactions (Christian et al., 2017 ▸), triboluminescence (Kuchison et al., 2009 ▸), and enzyme inhibition (Zhang et al., 2014 ▸; Fonteh & Meyer, 2009 ▸). To this end, our group has been developing synthetic routes to unsymmetric tri­aryl­phosphines, their chalcogenide derivatives and the resultant metal–ligand complexes (Luster et al., 2022 ▸). While attempting to prepare a complex between gold(I) and the selenide derivative of diphenyl-2-thienylphosphine, we isolated single crystals of the title compound as a decomposition product.

Structural commentary

The structure of compound I was solved in the ortho­rhom­bic space group P212121 with a Flack parameter of −0.002 (6) (Parsons et al., 2013 ▸). The phospho­rus–gold and chloride–gold bond lengths are 2.226 (2) and 2.287 (2) Å, respectively. The phenyl and thienyl rings of the ligand are disordered, with the thienyl ring being distributed over all three possible positions at the P atom. The relative occupancy ratio between these positions was found to be 0.406 (3):0.406 (2):0.188 (2). Furthermore, the thienyl ring position with a relative occupancy of 0.406 (3) was modeled as two rotational isomers around the C—P bond with a relative occupancy ratio of 0.279 (3):0.128 (3) (see the Refinement section for further details of the treatment of the disorder). The atom-labeling scheme for the predominant moiety (Part 1: phenyl rings C1–C6 and C14–C19 as well as thienyl ring S1C and C1C–C4C) is shown in Fig. 1 ▸.

The coordination geometry of the gold center is nearly linear with a P1—Au1—Cl1 bond angle of 179.42 (9)°. With regard to the phosphine ligand, for the most prevalent moiety the P—C bond lengths are 1.769 (7), 1.786 (7) and 1.874 (14) Å. The geometry around the phospho­rus atom P1 resembles a tetra­hedron with a τ4 descriptor for fourfold coordination of 0.95 (where 0.00 = square planar, 0.85 = trigonal pyramidal, and 1.00 = tetra­hedral; Yang et al., 2007 ▸). The C—P—C bond angles range from 105.3 (6) to 106.9 (11)°, and the Au—P—C bond angles range from 111.9 (5) to 113.6 (3)° for the most prelavent moiety.

Supra­molecular features

Individual mol­ecules of the title compound are held together through inter­molecular C—H⋯π inter­actions (Table 1 ▸). In Part 1, these inter­actions exist between the C14–C19 phenyl ring and the hydrogen atom C2C(H2C) of the thienyl ring as well as between hydrogen atom C18(H18) and the S1C/C1C–C4C thienyl ring. These inter­molecular C—H⋯π inter­actions link the mol­ecules together to form helices that propagate along the a-axis direction (Fig. 2 ▸). The helices are then held together through C—H⋯π inter­actions to form a complex 3D network (Fig. 3 ▸). The remainder of the inter­molecular C—H⋯π inter­actions present in this structure are not exclusive to Part 1, and are listed in Table 1 ▸.

Database survey

A search of the Cambridge Structural Database (CSD, Version 5.42, November, 2020; Groom et al., 2016 ▸) for structures containing a P—Au bond where the phospho­rus atom bears one thienyl ring resulted in 14 hits. Structures IHUJUQ (Ho & Tiekink, 2003 ▸) and IHUJUQ01 (Monkowius et al., 2003 ▸) are closely related to compound I, with a linear arrangement of chloride and one tris­(2-thien­yl)-substituted phosphine ligand bound to a gold(I) atom. Another related structure is IWAYUC (Yang et al., 2016 ▸), which contains a di­phenyl­phosphino-3-thienyl-1H-imidazole ligand again bound to a gold(I) atom that also bears a chloride. Finally, structure YAHPUT (Stott et al., 2005 ▸) features a terthio­phene-substituted di­phenyl­phosphinogold(I)–chloride complex.

Synthesis and crystallization

A small vial was charged with diphen­yl(2-thien­yl)phosphine selenide (10-15 mg; Luster et al., 2022 ▸) and a stoichiometric amount of chloro­(tetra­hydro­thio­phene)­gold(I). The solids were dissolved in 1 mL of CDCl3, and the reaction mixture was transferred to an NMR tube. Crystals of compound I were grown serendipitously via slow evaporation of the solvent.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All hydrogen atoms were placed in calculated positions and refined as riding: C—H = 0.95–1.00 Å with U iso(H) = 1.2U eq(C). The electron density corresponding to the disordered phenyl rings and the thienyl ring was modeled over three parts. In the model, electron density corresponding to the thienyl ring was found at three positions on the phospho­rus atom. In one of these positions, the thienyl ring was also found to be present as two rotational isomers corresponding to a 180° rotation around the C—P bond. The relative occupancies of each position of the thienyl ring were refined, while the total occupancy of all thienyl sites as well as the occupancy sum of each site were constrained to unity using SUMP commands. The thienyl occupancy rates refined to be 0.406 (2):0.278 (3):0.128 (3):0.188 (2) for the sites of S1C, S1B, S1A and S1D. Bond lengths and angles of all four thienyl moieties were restrained to be similar to each other using SHELXL (Sheldrick, 2015b ▸) SAME commands with an esd of 0.001 Å. For the pivot moiety with the highest occupancy (S1C/C1C–C4C), distance restraints were used to ensure a model with bond lengths and angles that agree with known values. Bonds of the thienyl ring were restrained using DFIX commands to be 1.70 (S1C—C1C), 1.34 (C1C—C2C, C3C—C4C) and 1.41 (C2C—C3C) Å with an esd of 0.002 Å in SHELXL (Sheldrick, 2015b ▸). The less occupied thienyl rings A and B were also restrained to be planar and coplanar with the P atom using FLAT commands. All P1—C distances were restrained to be similar to each other using SADI commands. The atoms of each phenyl ring C1–C6, C7–C13 and C14–C15 were constrained to resemble an ideal hexa­gon with C—C bond lengths of 1.39 Å using SHELXL AFIX 66 commands. Lastly, U ij components of all C, S and P atoms were restrained to be similar to each other for atoms closer than 2.0 Å with an esd of 0.002 Å2.

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.
