摘　　要：利用二苄基二氯化锡与三苯基氧膦反应 ,合成了目标化合物二苄基二氯化锡三苯基氧膦 ,其结构经元素分析表征。用X 射线单晶衍射测定其晶体结构属于三方晶系 ,空间群为P2 1,a =2 .0 2 7( 4 )nm ,b =0 .9714 ( 17)nm ,c =1.5 5 9( 3)nm ,α =90° ,β =90° ,γ =90° ,Z =4 ,V =3.0 4 9( 10 )nm3 ,Dc =1.4 0 7mg·m-3 ,u =1.0 81mm-1,F( 0 0 0 )=1312 ,R1=0 .0 370 ,wR2 =0 .0 6 88。Triphenylphosphine oxide)dibenzyltin dichloride was synthesized by the reaction of dibenzyltin dichloride with triplhenylphosphine oxide and characterized by elemental analysis. The crystal structure was determinded by X-ray single crystal diffraction. The crystal belongs to trigonal system with space group P2 1, a=2.027(4)nm, b=0.9714(17)nm, c=1.559(3)nm, α=90°, β=90°, γ=90°, Z=4, V=3.049(10)nm 3, Dc=1.407 mg·m -3 , u=1.081mm -1 , F(000)=1312, R 1=0.0370, wR 2=0.0688. In the crystal structure the tin atoms are five-coordinated adopting a distorted trigonal bipyramidal structure.
