Crystal structure of (1,3-di-methyl-thio-urea-κS)tris-(tri-phenyl-phosphane-κP)silver(I) acetate.

In the mononuclear title salt, [Ag(C3H8N2S)(C18H15P)3](CH3COO), the Ag(I) ion exhibits a distorted tetra-hedral coordination sphere defined by three P atoms from three tri-phenyl-phosphane ligands and one S atom from a 1,3-di--methyl-thio-urea ligand. In the crystal, the acetate anion is linked with the complex cation via duplex N-H⋯O hydrogen bonds [graph-set motif R (2) 2(8)].

(Aceto-nitrile-κN)iodidobis(tri-phenylphosphane-κP)copper(I).

In the mononuclear title complex, [CuI(CH3CN)(C18H15P)2], the Cu(I) ion is in a distorted tetra-hedral geometry, coordinated by two P atoms of two tri-phenyl-phosphane ligands, one N atom of an aceto-nitrile ligand and one iodide anion. The aceto-nitrile ligand is disordered over two sets of sites in a 0.629 (15): 0.

(N,N'-Di-ethyl-thio-urea-κS)tris-(triphenylphosphane-κP)silver(I) acetate methanol monosolvate.

In the mononuclear title complex, [Ag(C5H12N2S)(C18H15P)3](CH3COO)·CH3OH, the Ag(I) ion is in a distorted tetra-hedral coordination geometry formed by three P atoms from three tri-phenyl-phosphane ligands and one S atom from an N,N'-di-ethyl-thio-urea ligand. In the crystal, the acetate anion is connected to the complex mol-ecule via a pair of N-H⋯O hydrogen bonds [graph-set motif R (2) 2(8)] and the solvent methanol mol-ecule is connected to the anion via an O-H⋯O hydrogen bond. This aggregate is further connected through a weak C-H⋯O hydrogen bond, forming a chain along [100].
