摘　　要：利用二苄基二氯化锡和二甲基氨荒酸盐反应,合成了氯代二苄基锡二甲基氨荒酸酯.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.用X-射线单晶衍射测定了该化合物的晶体结构.它属于三斜晶系,空间群为P1,a=0.75750(15),b=1.0615(2),c=1.2059(2)m,α=95.053(3)°,β=95.539(4)°,y=99.113(4)°,z=2,V=0.9476(3)nm3,Dx=1.600g/cm3,μ=1.705mm-1,F(000)=456,R1= 0.0409,wR2=0.1194[I≥2 σ(I)].分子中锡原子的配位数为5,形成一个严重扭曲的三角双锥构型,并且化合物以弱桥联二聚体存在.Chlorodibenzyltin dimethyldithiocarbamate was synthesized by the reaction of dibenzyltin dichloride with dimethyldithiocarbamate and characterized by elemental analysis, IR and H-1 NMR. The crystal structure was determined by X-ray single crystal diffraction. The crystallographic data are as follows: triclinic, space group P1, a = 0.75750 (15), b = 1.0615(2), c = 1.2059(2) nm, alpha = 95.053(3)degrees, beta = 95.539(4)degrees, gamma = 99.113(4)degrees, Z = 2, V = 0.9476 (3) nm(3), D-x = 1.600 g, mu = 1.705 mm(-1), F(000) = 456, R-1 = 0.0409, wR(2) = 0.1194[1 greater than or equal to 26(I)]. The structure consists of discrete molecules containing five-coordinate tin atoms in a seriously distorted trigonal bipyramidal configuration. The molecules are packed in the unit cell as weakly-bridged dimmers.
