Synthesis and characterization of Pd(II) and Pt(II) complexes containing mixed ligands of thione and diamine

New Pd(II) and Pt(II) complexes of the type [M(bzoS)2(diamine)] {where M = or } from treatment one mole diamine ligands {diamine , phenanthroline (Phen), bipyridine (Bipy), ethylene (en), N,N′-dimethyl (dmen)} with [M(bzoS)2] complexes. The prepared were characterization by elemental analysis (CHN), molar conductivity, infrared spectroscopy, nuclear magnetic resonance proton (1H NMR). bzoS- ligand was bonded as monodentate through sulfur atom whereas bidentate fashion via nitrogen atoms to give a square planner arrangement round Pd Pt ions.
