Metal complexes of general formula M(ttz)2X2 (with M= Pd(II) or Pt(II); X = Cl or Br; ttz = 1,3-thiazolidine-2-thione) have been synthetized as crystalline compounds and studied by means of X-rayPhotoelectronSpectroscopy (XPS). The chemical shift of core level signals showed that ttz is bonded to the metal through the thioketonic sulphur atom and that electronic charge redistribution in the ligand
通式为M(ttz)2X2的金属配合物(M = Pd(II)或Pt(II); X = Cl或Br; ttz = 1,3-噻唑烷-2-硫酮)已经合成为结晶化合物并进行了研究通过X射线光电子能谱(XPS)。核心能级信号的化学位移表明ttz通过硫代酮硫原子与金属键合,配体中的电荷重新分布在络合后发生。不存在金属-氮键。这与所有量子力学模型的结果一致,根据该模型,即使在氢键配合物中,氢也会与氮结合,从而使后者相当不易配位
