二[(三甲基硅基)亚甲基]锡(Ⅳ)Schiff碱配合物的合成和结构表征

Synthesis and structure of bis[(trimethylsilyl) methylene]tin complexes of Schiff base

用二[(三甲基硅基)亚甲基]二氯化锡和水杨醛缩氨基酸Schiff碱,以1∶1的物质的量比在三乙胺存在下进行反应,合成了5个新的标题化合物,利用IR、1HNMR和MS对它们的组成和结构进行了表征。测试结果表明,在目标化合物的分子中,中心锡原子与氮原子发生配位,形成了五配位的三角双锥结构。

Five bis [ （ trimethylsilyl ） methylene ] tin Schiff base complexes were synthesized by the reaction of bis [ （trimethylsilyl）methylene] tin dichloride with Schiff base derived from amino acids and salieylaldehyde in the presence of triethylamine, and were characterized by IR, ^1HNMR and MS.The results indicated that the Sn atom in bis[ （ trimethylsilyl）methylene] tin Schiff base complexes was five-coordinated in trigonal bipyramidal geometries thanks to the existence of intermolecular ligands of Sn←N.
