Synthesis,Characterization and Investigation of Structures by X-ray Diffraction of Bis(tricyclohexyltin)Tetrachlorophthaloy Carboxylate

合成了双(三环己基锡)邻苯二甲酸酯Cl4C6(CO2Sn(C6H11)3)2,利用元素分析仪和IR表征了其结构。通过X-射线单晶衍射仪,测定了该配合物的晶体结构。该化合物晶体属单斜晶系,空间群P-1,a=14.552 2(13),b=13.365 1(12),c=34.006(3)(),β=97.899 0(10)°,Z=4,V=6 551.2(10)nm3,R=0.060 3,Rw=0.128 7,S=1.185。该分子是通过苯环桥联的双核有机锡化合物,分子中的两个锡原子均为畸变的四面体构型。

The bis （tricyclohexyltin） tetrachlorophthaloy carboxylate C14C6 （CO2Sn （C6H11） 3） 2 had been prepared and characterized by elemental analysis and IR. The crystal structure was determined by X-ray spectroscopic analysis. The crystal belongs to monoclinic space group P-1 with a=14.552 2 （13）, b=13.365 1 （12）, c=34.006 （3） （^°A）, β=：97.899 0 （10） °, Z=4, V=6 651.2 （10） nm^3, R=0.060 3, Rw=0.128 7, S= 1.185. The results indicate that the compound is binuclear organotin compound linked by the phenylcircle, and both the tin atoms existed respectively in a distorted tetrahedral environment.
