Triphenyltin thiobenzoate was synthesized by the reaction of triphenyltin chloride with thiobenzoic acid in the presence of Et3N. The title complex was characterized by elemental analysis, IR and JH NMR spectra, and its crystal structure was determined by X-ray single crystal diffraction study. The crystal belongs to orthorhombic with space group P2_12_12_1, a =0.8306(3) nm, 6 = 1.6906(5) nm, c = 3.1459 (10) nm, V = 4.417(2) nm~3, Z = 8, D_c = 1.465 g/cm~3, R_1 = 0.0472, wK_2 = 0.1012. In the crystals, the structure consists of discrete molecule containing four-coordinate tin atom in a distorted tetrahedral configuration.
