Antimony and bismuth dithiocarboxylates of the type [M(S2CAr)(3)] (M = Sb, Bi; Ar = C6H5 (Ph), 4-MeC6H4 (tol)) have been synthesized. These complexes were characterized by elemental analysis, IR, UV-Vis, and H-1 NMR spectroscopy. X-ray crystal structural analyses of [Sb(S(2)Ctol)(3)] and [Bi(S2CPh)(3)] showed that the dithiocarboxylates are asymmetrically chelated to metal atom. The latter acquires a distorted pentagonal pyramidal geometry as a consequence of the presence of a stereochemically active lone pair of electrons. Pyrolysis of these complexes either in a furnace or in refluxing diphenylether gave M2S3 as characterized by their XRD pattern and EDAX analysis.
