英文摘要：

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.
