[(Z)-O-Methyl-N-propylthiocarbamato-[kappa]S](triphenylphosphine-[kappa]P)gold(I)

P. P. Tadbuppa and E. R. T. Tiekink

Abstract top

In the title compound, [Au(C5H10NOS)(C18H15P)], the AuI atom is linearly coordinated within an S,P-donor set with distortion from an ideal linear geometry [S-Au-P = 176.71 (6)°] due to an intramolecular Au...O contact [2.943 (4) Å]. In the crystal structure, centrosymmetrically related molecules associate via C-H...O interactions.

Comment top

The structure of the title compound, (I), was determined as a part of an on-going study of the structural systematics, including luminescence properties, of molecules related to 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).

The Au atom exists within the expected linear geometry defined by the S and P donor atoms. The C1–S1 and C1═N1 bond distances of 1.775 (7) and 1.265 (8) Å, respectively, confirm that the carbonimidothioate ligand is functioning as a thiolate. The small deviation from linearity about the Au atom is ascribed to the close approach of the O1 atom, Au···O1 is 2.943 (4) Å. The most prominent intermolecular interaction occurring in the crystal structure is a C–H···O contact, Table 1, which occurs between centrosymmetrically related molecules leading to a dimeric aggregate, Fig. 2.

For structural systematics and luminescence properties of phosphinegold(I) carbonimidothioates, see: Ho et al. (2006); Ho & Tiekink (2007); Kuan et al. (2008). For the synthesis, see Hall et al. (1993).

Experimental top

Compound (I) was prepared following the standard literature procedure from the reaction of Ph3PAuCl and MeOC(S)N(H)Pr in the presence of base (Hall et al., 1993).

Refinement top

The H atoms were geometrically placed (C—H = 0.94–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The maximum and minimum residual electron density peaks of 1.41 and 2.23 e Å-3, respectively, were located 0.82 Å and 1.59 Å from the Au and H20 atoms, respectively.

Special details top

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.
