THE MOLECULAR-STRUCTURE OF DIBUTYLBIS(2-PYRIDINETHIOLATO-5-ETHYL ESTER)TIN(IV), [SNBU(2)(TNEE)(2)]

The crystal structure of [SnBu(2)(TNEE)(2)], (HTNEE = 5-ethyl ester of 2-mercaptopyridine-5-carboxylic acid) has been determined by X-ray si ngle crystal diffraction study. The crystal is triclinic, space group <P(1)over bar>, a = 10.042(1), b = 18.421(2), c = 7.979(1) Angstrom, a lpha = 98.7(1), beta = 107.3(1), gamma = 87.7(1)degrees, V = 1393(1) A ngstrom(3), and Z = 2 The tin center is coordinated to two butyl group s and to the nitrogen and the sulfur atoms of two ligand molecules in a very distorted trapezoidal bipyramid.
