Abstract
Three different thiosemicarbazone (TSC) ligands, BTSC, ClTSC, and MeTSC, derived from benzophenone, p-chlorobenzaidehyde, and m-methoxybenzaldehyde, respectively, were complexed with K2PtCl4. The structures of the complexes were determined on the basis of elemental analyses, IR and H-1, N-15, and C-13 NMR spectral studies, which support the formation of square-planer dimeric complexes of the type [LPtCl2PtL], where L is MeTSC and CITSC, which are N,S containing bidentate ligands. The complex prepared with the ligand BTSC is of the type [L2PtCl2] where L acts as a monodendate ligand as confirmed by CHN analyses. X-ray powder analyses show that the complexes are crystalline.
