چکیده
A nearly linear coordination geometry for Au is found in the title compound, [Au(C(9)H(9)N(2)O(3)S)(C(21)H(21)P)]. The thio-carbamate ligand is orientated so that the aryl group is in close proximity to the Au atom, consistent with an Au⋯π contact [Au⋯Cg = 3.351 (5) Å; Cg is the centroid of the aromatic ring].

In the title compound, [Au(C(5)H(10)NOS)(C(21)H(21)P)], two independent mol-ecules comprise the asymmetric unit, and these are connected by an aurophilic inter-action [Au⋯Au = 3.1351 (3) Å]. Each Au(I) atom is linearly coordinated within a S,P-donor set with the distortion from ideal linear geometry [S-Au-P = 175.31 (5) and 176.45 (5)°] ascribed to an intra-molecular Au⋯O contact in each case [...

An S,P-donor set in the title solvate, [Au(C(9)H(9)N(2)O(3)S)(C(18)H(15)P)]·CH(2)Cl(2), defines a linear geometry for the Au(I) atom [S-Au-P = 177.75 (7)°], with the minor distortion ascribed to the influence of an intra-molecular Au⋯O contact [3.019 (6) Å]. In the crystal, the packing is stabilized by a network of C-H⋯S, C-H⋯N and C-H⋯O contacts.

The title phosphanegold(I) thiol-ate compound, [Au(C9H9N2O3S)(C21H21P)], is a second monoclinic polymorph (space group P21/c) that complements a previously reported Cc polymorph [Broker & Tiekink (2008 ▸). Acta Cryst. E64, m1582]. An SP donor set defines an approximately linear geometry about the gold atom in both forms. The key distinguishing feature between the present structure and the previ...

In the title compound, [AgCl(C7H7N3O2S)(C18H15P)2], the AgI ion is in a distorted tetra-hedral coordination environment formed by P atoms from two tri-phenyl-phosphane ligands, one terminal S atom from the 1-(4-nitro-phen-yl)thio-urea ligand and a chloride ion. In the crystal, bifurcated (N-H)2⋯Cl hydrogen bonds [with graph-set motif R21(6)] connect complex mol-ecules, forming zigzag chains alo...
متن کامل[(Z)-O-Ethyl N-(4-nitrophenyl)thiocarbamato-κS](triethylphosphine-κP)gold(I)
In the title compound, [Au(C(9)H(9)N(2)O(3)S)(C(6)H(15)P)], two virtually identical mol-ecules comprise the asymmetric unit. 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 intra-molecular Au⋯O contacts [2.993 (5) and 2.957 (5) Å] is responsible for the slight deviations from the ideal linear coordinatio...
