The intramolecular O→Sn coordination bond in (Z) - 1 - [2- (dihalophenylstannyl) vinyl] -cyclooctanol, a proposed indication for the antitumour activity of organotin compounds, was dissociated and re - coordinated by N - containing bidentate ligands, and formed new organotin complexes. These new complexes were characterized by IR, 1HNMR, elemental analysis and molar conductance determination. Especially, the correlation between 1HNMR spectroscopy and dissociation was discussed in detail: The larger the chemical shifts of proton in olefinic bonds, the higher the coordination yields.%用具有抗癌活性的(Z)-1-[2-(二卤化苯基锡基乙烯基)]-环辛醇与含氮的双齿配体作用,合成了一系列新的有机锡络合物,通过IR,1HNMR,元素分析和摩尔电导值的测定对其结构、性质进行了表征,特别对有机锡化合物分子内O→Sn配位键的离解与配体中烯基质子化学位移(1HNMR)的相关性进行了讨论.
