1,4-环己二酸三烃基锡(Ⅳ)的合成及结构研究

Synthesis and Crystal Structures of Triorganotin with 1,4-Cyclohexanedicarboxylic Acid

用1,4-环己二酸分别与三苯基氯化锡,三甲基氯化锡,三丁基氯化锡,三苄基氯化锡反应,得到了[(Ph3Sn)2](C8H10)(COO)2]1,(Me3Sn)2[(C8H10)(COO)2]2,[(n-Bu)3Sn]2[(C8H10)(COO)2]3和[(PhCH2)3Sn]2[(C8H10)(COO)2]4四个新型的化合物,并通过元素分析、红外光谱和核磁共振氢谱对其结构进行了表征.其中化合物1还通过X-射线单晶衍射进行了表征.单晶结构表明配合物1是一个二锡核的单体三苯基锡化合物,在配合物1中羧酸配体上的两个羧基都参与了配位,中心锡原子都是扭曲的四配位的四面体构型.

Four new compounds[（Ph3Sn）2]（C8H10）（COO）2] 1,（Me3Sn）2[（C8H10）（COO）2] 2,[（n - Bu）3 Sn]2 [（C8 H10） （COO）2 ] 3 和 [ （PhCH2）3 Sn]2 [（C8 H10 ） （COO）2 ] 4 have been synthesized by the reaction of trans-1, 4-Cyclohexane dicarboxylic acid and triphenyltin, trimethyltin, tributyltin, tribenzyltin. All the compounds have been characterized by element analyses, IR spectra, 1H NMR spectra. The compound 1 is also characterized by X-ray diffraction crystallography. The data indicated that compound 1 is a dinuclear monomer, both of the carboxyl derived from the trans-1,4-Cyclohexanedicarboxylic acid coordinating to the tin atoms. The coordination geometry about the Sn atoms are distorted trigonal bipyramidal geometry.
