用三苯基氯化锡与戊二酸二钠反应,合成了双(三苯基锡)戊二酸酯,Ｘ－射线单晶衍射表明,该化合物属三方晶系,空间群Ｃ２２２１,晶胞参数:ａ＝１．５０７５(５)ｎｍ,ｂ＝４．８０２(１７)ｍｎ,ｃ＝２．８９４ ４(９)ｎｍ,α＝９０°,β＝９０°,γ＝９０°,Ｖ＝２０．９５３(１２)ｎｍ３,Ｚ＝８,Ｄｃ＝１．３１６ｇ/ｃｍ３,μ＝１．２２６ｍｍ－１,Ｆ(０００)＝８２８０,Ｒ１＝０．０５４ ６,ｗＲ２＝０．１１８ ２．晶体结构中存在５种化学环境不同的三角双锥构型的锡原子,由于配体中两个羧基在不同方向的交联作用,使化合物呈现三维骨架结构． The bis (triphenyltin) glutarate was synthesized by the reaction of triphenyltin chloride with disodium glutarate. The X-ray single crystal diffraction indicated that the compound belongs to the trigonal system with space group C2221, unit cell A = 1.5075 (5) nm, b = 4.802 (17) mn, c = 2.894 4 (9) nm, α = 90 °, β = 90 °, γ = 90 °, V = 20.953 (12) nm3, Z = 8, Dc = 1.316 g / cm3, μ = 1.226 mm-1, F (000) = 8280, R1 = 0.054 6, wR2 = 0.118 2. In the crystal structure, there are five kinds of tin atoms with triangular double cones in different chemical environments. Due to the cross-linking of two carboxyl groups in different directions in the crystal structure, the three-dimensional skeleton structure of the compound appears.
