三甲基锡丙酮酸-2-噻吩甲酰腙的合成及晶体结构

摘要

利用三甲基氯化锡与丙酮酸-2-噻吩甲酰腙反应,合成了新的三有机锡希富碱衍生物{Me3Sn[C4H3SC(O)NHN=C(CH3)COO]}n,并用元素分析、红外光谱、核磁共振氢谱和X-射线单晶衍射对该化合物进行了表征.测试结果表明,在配合物中锡原子为五配位的三角双锥配位环境.化合物通过羧基氧原子的桥连作用形成了一维无限链状结构.%A new trimethyltin(IV) compound with Schiff base of pyruvic acid thiophene-2-carboxylic hydrazone {Me3Sn[C4H3SC(O)NHN=C(CH3)COO]}n was synthesized by the reaction of Me3SnCl with pyruvic acid thiophene-2-carboxylic hydrazone.This compound has been characterized by elemental,IR,1H NMR analyses and X-ray crystallographic diffraction analyses.In compound,the tin atoms are five-coordinate in a distorted trigonal bipyramid coordination field included a bridging O atom from the carboxylate,forming the one-dimensional infinite chain organotin structrue.
