摘　　要：在碱性条件下,用二苄基二氯化锡与铋试剂-Ⅰ反应,意外发生了C-S键断裂反应,生成了非预期产物,经X-射线表征了产物的结构.该晶体属于单斜晶系,空间群为P21/n,a=1-0910(4)nm,b=0.9054(3)nm,c=2.0925(8)nm β=94.174(7)°,Z=4,V=2.0613(13)nm3,Dc=1.725 mg/m3,μ=1.656 mm-1,F(000)=1064,R1=0.0475,wR2=0.1109.中心原子锡为六配位形式.A complex of organotin was synthesized by the reaction of dibenzyltin dichloride with 2,5-dimercapto-l,3,4-thiodiazole. During the reaction,under a very gentle condition,one of carbon-sulfur bonds cleaved. The weak interactions between tin and nitrogen atoms make the compound a dimmer and the coordination number of tin atom ambiguous. The high atom interactions between adjacent sulfur atoms connected the dimers to form a two-dimensional plane.
