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 H-1 NMR spectra, and its crystal structure was determined by X-ray single crystal diffraction study. The crystal belongs to orthorhombic with space group P2(1)2(1)2(1), a = 0.8306(3) nm, b = 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, wR(2) = 0.1012. In the crystals, the structure consists of discrete molecule containing four-coordinate tin atom in a distorted tetrahedral configuration.
