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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
