Triphenyltin 2-thiophenecarboxylate was synthesized by reaction of sodium 2-thiophenecarboxylate and characterized by IR, 1H NMR and MS spectroscopy. The crystal structure was determined by X-ray single crystal diffraction study. The compound crystallizes in monoclinic space group P2 1/n, with a=1.3429(7) nm, b=1.11773(6) nm, c=1.4241(8) nm, β=116.519(6)°, V=2.0146(18) nm 3, Z=4, D c=1.573 g/cm 3, R 1=0.0391, wR 2=0.0943. In unit, there are four-coordinate tin atoms in a distorted tetrahedral configuration.
