The Au atom in the title compound, [Au(C8H7ClNOS)(C18H15P)], exists within a slightly distorted linear geometry defined by an S,P-donor set [S—Au—P angle = 174.61 (4)°], with the distortion related to a short intramolecular Au⋯O contact [2.988 (3) Å]. In the molecules are arranged into supramolecular chains along the b axis by C—H⋯π interactions.

Compound (I) was prepared following the standard literature procedure from the reaction of Ph3AuCl and MeOC(═S)N(H)(C6H4Cl-3) in the presence of NaOH (Hall et al., 1993). Crystals were obtained by the slow evaporation of a CHCl3/hexane (3/1) solution held at room temperature.
The H atoms were geometrically placed (C—H = 0.94–0.97 Å) and refined as riding with Uiso(H) = 1.2-1.5Ueq(C). The maximum and minimum residual electron density peaks of 1.16 and 1.21 e Å-3, respectively, were located 0.84 Å and 0.88 Å from the Au atom.
The remarkable propensity of molecules with the general formula R3PAu[SC(OR')═ NR''], for R, R' and R'' = alkyl and aryl, to provide diffraction quality crystals have proved useful for systematic crystal engineering studies (Ho et al., 2006; Ho & Tiekink, 2007; Kuan et al., 2008). The structure of the title compound, (I), was investigated in the context of the above.
The nearly linear SP coordination geometry observed for the Au atom in (I), Fig. 1, is defined by phosphine and thiolate ligands, Table 1. The deviation from the ideal linearity [S—Au—P = 174.61 (4) °] is related to a short intramolecular Au···O contact [2.988 (3) Å]. With the exception of the p-tolyl derivatives (Kuan et al., 2008), the overall
(including close Au···.O contacts) conforms to the majority of related compounds having monodentate phosphine ligands.The major feature of the crystal packing is the presence of C–H···π interactions that lead to the formation of supramolecular chains along the b axis, Fig. 2 and Table 2. Notably, the Cl-substituted benzene ring accepts two such interactions also donates one. Chains are arranged into layers in the (1 0 1) plane, Fig. 3.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The remarkable propensity of molecules with the general formula R3PAu[SC(OR')═ NR''], for R, R' and R'' = alkyl and aryl, to provide diffraction quality crystals have proved useful for systematic crystal engineering studies (Ho et al., 2006; Ho & Tiekink, 2007; Kuan et al., 2008). The structure of the title compound, (I), was investigated in the context of the above.
The nearly linear SP coordination geometry observed for the Au atom in (I), Fig. 1, is defined by phosphine and thiolate ligands, Table 1. The deviation from the ideal linearity [S—Au—P = 174.61 (4) °] is related to a short intramolecular Au···O contact [2.988 (3) Å]. With the exception of the p-tolyl derivatives (Kuan et al., 2008), the overall molecular conformation (including close Au···.O contacts) conforms to the majority of related compounds having monodentate phosphine ligands.
The major feature of the crystal packing is the presence of C–H···π interactions that lead to the formation of supramolecular chains along the b axis, Fig. 2 and Table 2. Notably, the Cl-substituted benzene ring accepts two such interactions also donates one. Chains are arranged into layers in the (1 0 1) plane, Fig. 3.
