邻溴苄基溴或对溴苄基溴与锡反应合成三(邻溴苄基)溴化锡(1)和四(对溴苄基)锡(2).经X射线方法测定了新化合物的晶体结构.晶体结构1属斜方六面体晶系,空间群为R-3,晶体学参数:a=1.3389(3) nm, b=1.3389(3) nm, c=2.1896(8) nm, V=3.3993(16) nm3, Z=6, Dx=2.077 Mg?m-3, μ(Mo Kα)=81.83 cm-1, F(000)=2004, R1=0.0477, wR2=0.1372;晶体结构2属正交晶系,空间群为Fdd2,晶体学参数:a=2.1027(7) nm, b=2.3034(8) nm, c=1.1431(4) nm, V=5. 536(3) nm3, Z=8, Dx=1.917 Mg?m-3, μ(Mo Kα)=67.11 cm-1, F(000)=3056, R1=0.0358, wR2=0.0659.化合物1中Sn-C键长为0.2160(8) nm, Sn-Br键长为0.2491(3) n...

The n-butyl alcohol solution of o-bromobenzyl bromide or p-bromobenzyl bromide and Sn was heated at reflux for 6 h to yield tri(o-bromobenzyl)tin bromide (1) and tetra(p-bromobenzyl)tin (2). The crystal and molecular structures of compounds 1 and 2 were determined by X-ray diffraction analysis. The crystal 1 is rhombohedral, space group R-3 with a = 1.3389(3) nm, b = 1.3389(3) nm, c = 2.1896(8) nm, V = 3.3993 (16) nm3, Z = 6, D x = 2.077 Mg·m-3, μ(Mo Kα) = 81.83 cm -1, F(000) = 2004, R1 = 0.0477, wR2 = 0.1372. The crystal 2 belongs to orthor...
