μ-氧-双(三苄基)锡的合成与表征

Synthesis and characterization of the μ-oxygen-bis(tribenzyl) tin

在乙醇钠存在条件下,三苄基氯化锡发生水解,获得无色的μ-氧-双(三苄基)锡晶体,通过元素分析、红外光谱、核磁共振和X-射线单晶衍射对其结构进行表征。化合物晶体属正交晶系,R3空间群。晶胞参数为:a=b=c=0.9636(3)nm,α=β=γ=84.085(3)°,Z=1,V=0.8812(4)nm3。化合物是由两个中心锡原子组成一个结构单元的四配位线性配合体。

μ-Oxygen-bis（tribenzyl）tin was synthesized by the reaction of（PhCH2）3SnCl with sodium ethoxide.The crystal structures of the title compound were characterized by element analysis,IR,1HNMR and X-ray diffractometry.The crystal was of the rhombohedral structure with a space group of R3,a=b=c=0.963 6（3）nm,α=β=γ=84.085（3）°,Z=1,and V=0.881 2（4）nm3.In this structure,the tin had a distorted tetrahedral geometry with two tin atoms consisting of a four-coordinated unit.
