摘　　要：合成了两种具有新型结构的苄基锡化合物:一维链状μ-氯-三苄基锡(1)和一维链状μ-氧-三苄基锡(2),经X-射线方法测定了化合物的晶体结构。晶体结构(1)属正交晶系,空间群为P212121,晶体学参数:a=0.8553(3)nm,b=1.0814(4)nm,c=1.9681(7)nm,V=1.8204(11)nm3,Z=4,Dc=1.560g·cm-3,μ(MoKα)=15.47cm-1,F(000)=856,R1=0.0597,wR2=0.1415。晶体结构(2)属正交晶系,空间群为P212121,晶体学参数:a=1.9823(4)nm,b=1.0891(2)nm,c=0.8611(17)nm,V=1.8590(6)nm3,Z=4,Dc=1.458g·cm-3,μ(MoKα)=13.76cm-1,F(000)=820,R1=0.0327,wR2=0.0648。配合物中锡原子均呈五配位畸变三角双锥构型。Two novel complexes μ-chlorine-tribenzltin (1) and μ-oxygen-tribenzltin (2) with the one-dimensional infinite were synthesized. The crystal structures of compounds were determined by X-ray diffraction. The crystal of (1) belongs to Orthorhombic space group P212121 with a=0.855 3(3), b=1.081 4(4), c=1.968 1(7) nm, V=1.820 4(11) nm3, Z=4,Dc=1.560 g·cm-3, μ(Mo Kα)=15.47 cm-1, F(000)=856, R1=0.059 7, wR2=0.141 5. The crystal of (2) belongs to Orthorhombic space group P212121 with a=1.982 3(4), b=1.089 1(2), c=0.861 1(17) nm, V=1.859 0(6) nm3, Z=4, Dc=1.458 g·cm-3, μ(Mo Kα)=13.76 cm-1, F(000)=820, R1=0.032 7, wR2=0.064 8. The tin atoms in the crystal structures rendered five-coordinate in a distorted trigonal bipyramidal configurations. CCDC: 274181, 1; 274182, 2.
