The AuI atom in the title compound, [Au(C6H12NOS)(C18H33P)], is coordinated within a S,P-donor set that defines a slightly distorted linear geometry [S—Au—P angle = 173.44 (5)°], with the distortion due in part to a close intramolecular Au⋯O contact [3.023 (4) Å]. The N-bound isopropyl group is disordered over two orientations in a 0.618 (15):0.382 (15) ratio.

Compound (I) was prepared following the standard literature procedure from the reaction of Cy3PAuCl and EtOC(═S)N(H)(i-Pr) 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 = 0.97-0.99 Å) and refined as riding with Uiso(H) = 1.2-1.5Ueq(C). The maximum and minimum residual electron density peaks of 1.19 and 1.25 e Å-3, respectively, were located 0.84 Å and 1.20 Å from the Au atom. High thermal motion was noted in the iso-propyl substituent and two positions were resolved for each of the C atoms. Anisotopic
(constrained to be equivalent for paired components of the disorder, and approximately isotropic by the EADP and ISOR commands in SHELXL-97, respectively) and with the C–C distances restrained to 1.52±0.01 Å showed the major component of the disorder had a site occupancy factor = 0.618 (15).The investigation of the title compound, (I), forms a part of systematic structural studies of molecules with the general formula R3PAu[SC(OR')═ NR''] for R, R' and R'' = alkyl and aryl (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008).
In accord with the literature precedents, the gold atom in (I) exists within an SP donor set defined by the phosphine-P and thiolate-S atoms, Table 1 and Fig. 1. The coordination geometry is distorted from the ideal linear [S—Au—P = 173.44 (5) °] owing to the relatively close approach of the O1 atom, 3.023 (4) Å. The carbonimidothioate ligand is functioning as a thiolate as seen in the values of the C1–S1 and C1═N1 bond distances of 1.752 (5) and 1.254 (7) Å, respectively.

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 investigation of the title compound, (I), forms a part of systematic structural studies of molecules with the general formula R3PAu[SC(OR')═ NR''] for R, R' and R'' = alkyl and aryl (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008).
In accord with the literature precedents, the gold atom in (I) exists within an SP donor set defined by the phosphine-P and thiolate-S atoms, Table 1 and Fig. 1. The coordination geometry is distorted from the ideal linear [S—Au—P = 173.44 (5) °] owing to the relatively close approach of the O1 atom, 3.023 (4) Å. The carbonimidothioate ligand is functioning as a thiolate as seen in the values of the C1–S1 and C1═N1 bond distances of 1.752 (5) and 1.254 (7) Å, respectively.
