摘　　要：利用邻氟苄基氯和锡反应,合成了有机锡化合物(o-FC6H4CH2)2SnCl2。通过元素分析、红外光谱和核磁共振氢谱对其结构进行了表征。用X-射线单晶衍射测定了该化合物的晶体和分子结构。化合物晶体为单斜晶系,空间群C2/c,a=23.794(17),b=4.85(2),c=12.744(9),β=93.880(10)°,V=1467.8(18)3,Z=4,Dc=1.845Mg/m3,μ=2.109mm-1,R=0.0255,wR=0.0738。锡原子呈畸变四面体构型。通过化合物分子间Sn…Cl作用,形成一维链状结构。Organotin compound （o-FC6H4CH2）2SnCl2 has been synthesized by the reaction of o-FC6H4CH2Cl with Sn and characterized by elemental analysis, IR and ^1HNMR. The crystal and molecular structure have been determined by X-ray single crystal diffraction. A crystal of the compound is monoclinic with space group C2/c, a=23.794（17）A, b =4.85（2）A, c=12.744（9）A,β=93.880（10.）°, V=1467.8（18）A^3, Z=4, Dc =1.845Mg/m^3,μ=2.109mm^-1, R=0.0255, wR=0.0738. In the compound, the tin atom has distorted tetrahedral configuration. The molecules are packed in the unit cell in one-dimensional chain structure through a weak interaction between the chlorine atom and tin atom of an adjacent molecule.
