摘要
Metal complexes of general formula M(ttz)2X2 (with M = Zn(II) or Co(II); X = Cl or Br; ttz = 1,3-thiazolidine-2-thione) have been synthetized as crystalline (Br and Cl) and amorphous (chloride derivative only) compounds. LAXS (Large Angle X-ray Scattering) investigations reveal that the ttz ligand is bonded to the zinc or cobalt ion through one of the two sulphur atoms and no metal-nitrogen bonds are present. Detailed XPS (X-ray Photoelectron Spectroscopy) studies show that ttz is bonded to the metal through the thioketonic sulphur atom and that electronic charge redistribution in the ligand takes place after complexation.
