摘　　要：Treatment of 1,2-C6H4（SiH3）（SiH3） （1） with Pt（dmpe）（PEt3）2 （dmpe=Me2PCHeCH2PMe2） in the ratio of 1 ： 1 leads to the complex {1,2-C6H4（SiH2）（SiH2）}PtH （dmpe） （2）, which can react with proton organic reagent bearing hydroxy group with low steric hindrance to form a tetra-alkoxy substituted silyl platinum（II） compound （3）. Com- pounds 2 and 3 are the very rare examples of silyl transition-metal complexes derived from this chelating hydrosi- lane ligand. To the best of our knowledge, there are only 6 examples of silyl metal complexes prepared from this ligand with such structural features registered in the Cambridge Structural Database, among them, only one silyl platinum（II） compound is presented. The structures of complexes 2 and 3 were unambiguously determined by mul- tinuclear NMR spectroscopic studies and single crystal X-ray analysis.Treatment of 1,2-C6H4（SiH3）（SiH3） （1） with Pt（dmpe）（PEt3）2 （dmpe=Me2PCHeCH2PMe2） in the ratio of 1 ： 1 leads to the complex {1,2-C6H4（SiH2）（SiH2）}PtH （dmpe） （2）, which can react with proton organic reagent bearing hydroxy group with low steric hindrance to form a tetra-alkoxy substituted silyl platinum（II） compound （3）.
