摘要

The title complex [Ph3Sn(CH3OH) (terephthalate) (CH3OH) SnPh3] @2CH3OH was synthesized by the reaction of Ph3SnCl with terephthalate in the molar ratio of 2:1 in methanol solution and characterized by elemental analysis, IR and 1H NMR spectra, and the crystal structure was determined by X-ray single crystal diffraction study. The crystal belongs to monoclinic with space group P21/n, a = 1.5199(5) nm, b = 0.9000(3) nm, c=1.8206(6) nm, β=113.970(5)°, Z=2, V=2.2755(13) nm3, Dc= 1.413 g/cm3, μ= 1.146 mm-1, F(000) =980, R =0.0353, wR =0.0606. In the crystals of complex,the tin atoms rendered five-coordinate in a distorted tirgonal bipyramidal structure.
