The molecular structure of some transition metal complexes with 1,2,3,4-tetrazole-5-thiolate anions

The molecular structures of nine transition metal tetrazole-thiolates have been determined by X-ray structure determinations. The Ligand is invariably coordinated through its sulfur atom to the metal center [M = Pd-II, Cu-I, Ag-I, Au-I, Au-III, and Hg]. The M-S-C bond angles vary considerably, but this cannot be correlated with variations in the C-S bond lengths. Intermolecular association occurs for Ph3PAu(SCN4Me) via Au-S contacts, leading to dimeric strands in the solid state. The copper compound (Ph3P)(3)Cu-4(SCN4Me)(4) (5), possesses a rather asymmetric structure: one Cu atom is tricoordinated by 3 sulfur atoms, the other three are tetracoordinated by P and N as well as by S atoms.
