Syntheses,Structures and Vitro Anticancer Activities of μ_2-O-and μ_2-Dimethylglyoximato-bridged μ_3-O-Tris[di(m-fluorobenzyl)tin] Bis(dimethylglyoximate)

μ_2-O-and μ_2-dimethylglyoximato-bridged μ_3-O-trisdi(m-fluorobenzyl)tin] bis(dimethylglyoximate)(1) has been synthesized by the reaction of di(m-fluorobenzyl)tin dichloride with dimethylglyoxime. Complex 1 was characterized by means of IR,~1H NMR,elemental analysis and X-ray diffraction. It crystallizes in orthorhombic system,space group Pna21 with a = 2.22172(12),b = 1.05566(6),c = 2.15577(12) nm,V = 5.0561(5) nm~3,Z = 4,C_(50)H_(50)F_6N_4O_6Sn_3,Mr = 1273.01,Dc = 1. 6721 g/cm3,μ_(MoΚα) = 15.44 cm~(-1),F(000) = 2520,R = 0.0281 and wR = 0.0683. The stabilities,orbital energies and composition characteristics of some frontier molecular orbitals of 1 have been investigated with the quantum chemistry calculation. The properties of thermogravimetric and vitro anticancer activities of the compound have been discussed.
