In the title compound, [Au(C9H9N2O3S)(C6H15P)], two virtually identical molecules comprise the These are connected by Au⋯Au [3.6796 (4) Å] and Au⋯S [3.6325 (18) and 3.5471 (18) Å] contacts, forming a dimeric aggregate. The presence of intramolecular Au⋯O contacts [2.993 (5) and 2.957 (5) Å] is responsible for the slight deviations from the ideal linear coordination environments about the AuI ions. The conformation about the central C=N double bond is Z. Supramolecular chains sustained by π–π [3.573 (4) Å] and C—H⋯π interactions are evident in the These are connected into layers via weak intermolecular C—H⋯O interactions involving the nitro-group O atoms.

Compound (I) was prepared following the standard literature procedure from the reaction of Et3PAuCl and EtOC(S)N(H)C6H4NO2-4 in the presence of base (Hall et al., 1993). Yellow crystals were obtained from the layering of ethanol on a dichloromethane solution of (I); m. pt. 378–379 K. Analysis for C15H24AuN2O3PS: found (calculated): C: 33.57 (33.34); H: 4.80 (4.48); N: 5.09 (5.18); S: 5.61 (5.93). IR (cm-1): ν(C—S) 1102 s, 849m; ν(C—N) 1574m; ν(C—O) 1152 s. 31P{1H} NMR: δ 36.4 p.p.m.
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 1.64 and 0.90 e Å-3, respectively, were located 0.93 Å and 1.47 Å from the Au2 and Au1 atoms, respectively.
As part of an on-going study of the structural systematics, including luminescence properties, of phosphinegold(I) carbonimidothioates (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008), the title compound, (I), was investigated. Two independent molecules comprise the
Fig. 1, and these are virtually identical as seen in the r.m.s. values: 0.0105 Å for distances and 1.076 ° for angles (Spek, 2009). The molecules are connected by Au1···Au2 interactions, 3.6796 (4) Å, as well as Au1···S1A and Au2···S1 contacts of 3.6325 (18) and 3.5471 (18) Å, respectively, Fig. 1. In accord with expectation, the Au—S bond distances (Au—S = 2.3151 (16) and 2.3150 (16) Å) are longer than the Au—P distances (Au—P = 2.2590 (16) and 2.2596 (16) Å). Deviations from the ideal linear geometry defined by the S and P donor atoms (S—Au—P = 176.10 (6) and 174.04 (6) °) are traced to the close approach of the O1/O1a atoms (2.993 (5) and 2.957 (5) Å). The conformation about the central C1-N1 bond is Z. Finally, the C1—S1 (1.745 (7) and 1.769 (7) Å) and C1-N1 (1.276 (7) and 1.272 (8) Å) bond distances indicate that the ligand is binding as a thiolate.The structure of (I) is isomorphous with the methoxy analogue (Ho et al., 2006) and it is noted that there are no significant differences between comparable geometric parameters around the Au atoms.
Supramolecular chains aligned along the c direction are sustained by π–π [Cg1···Cg2 = 3.573 (4) Å and the dihedral angle between the rings is 3.7 (3) °, where Cg1 and Cg2 are the centroids of the C2—C7 and C2a—C7a rings, respectively; i: x, y, 1 + z] and C—H···π interactions, Table 1 and Fig. 2. Chains are linked into layers in the ac plane via C—H···O interactions, Table 1, where the O atoms are derived from the nitro groups; the O2 atom is bifurcated. Layers stack along the b direction, 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. |

As part of an on-going study of the structural systematics, including luminescence properties, of phosphinegold(I) carbonimidothioates (Ho et al. 2006; Ho & Tiekink, 2007; Kuan et al., 2008), the title compound, (I), was investigated. Two independent molecules comprise the asymmetric unit, Fig. 1, and these are virtually identical as seen in the r.m.s. values: 0.0105 Å for distances and 1.076 ° for angles (Spek, 2009). The molecules are connected by Au1···Au2 interactions, 3.6796 (4) Å, as well as Au1···S1A and Au2···S1 contacts of 3.6325 (18) and 3.5471 (18) Å, respectively, Fig. 1. In accord with expectation, the Au—S bond distances (Au—S = 2.3151 (16) and 2.3150 (16) Å) are longer than the Au—P distances (Au—P = 2.2590 (16) and 2.2596 (16) Å). Deviations from the ideal linear geometry defined by the S and P donor atoms (S—Au—P = 176.10 (6) and 174.04 (6) °) are traced to the close approach of the O1/O1a atoms (2.993 (5) and 2.957 (5) Å). The conformation about the central C1-N1 bond is Z. Finally, the C1—S1 (1.745 (7) and 1.769 (7) Å) and C1-N1 (1.276 (7) and 1.272 (8) Å) bond distances indicate that the ligand is binding as a thiolate.
The structure of (I) is isomorphous with the methoxy analogue (Ho et al., 2006) and it is noted that there are no significant differences between comparable geometric parameters around the Au atoms.
Supramolecular chains aligned along the c direction are sustained by π–π [Cg1···Cg2 = 3.573 (4) Å and the dihedral angle between the rings is 3.7 (3) °, where Cg1 and Cg2 are the centroids of the C2—C7 and C2a—C7a rings, respectively; i: x, y, 1 + z] and C—H···π interactions, Table 1 and Fig. 2. Chains are linked into layers in the ac plane via C—H···O interactions, Table 1, where the O atoms are derived from the nitro groups; the O2 atom is bifurcated. Layers stack along the b direction, Fig. 3.
