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)nm,α=95.053(3)°,β=95.539(4)°,Υ=99.113(4)°,Z=2,V=0.9476(3)nm^3,Dx=1.600g/cm^3,μ=1.705mm^-^1,F(000)=456,R1=0.0409,wR2=0.1194I≥2σ(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。

Synthesis, characterization and crystal structure of a weakly- bridged dimer chlorodibenzyltin dimethyldithiocarbamate

Chlorodibenzyltin dimethyldithiocarbamate was synthesized by the reaction of dibenzyltin dichloride with dimethyldithiocarbamate and characterized by elemental analysis, IR and ^1H 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, α=95.053(3)°, β=95.539(4)°, Υ=99.113(4)°, Z=2, V=0.9476(3) nm^3, Dx=1.600 g/cm^3, μ=1.705 mm^- ^1, F(000)=456, R1=0.0409, wR2=0.1194I≥2σ(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.
