N-BUTYLTRIS(2-PYRIMIDINETHIOLATO-N,S)TIN(IV)

The crystal structure of the title compound contains two crystallograp hically independent molecules. The 2-pyrimidinethiolato ligands (SPym) are bidentate. Sn-S bond distances range from 2.445 (4) to 2.561 (5) angstrom and Sn...N coordination is inferred from short Sn-N distances [2.470 (5)-2.622 (6) angstrom]. The coordination polyhedron around Sn in both molecules can be considered as a distorted pentagonal bipyram id. The pentagonal plane in each molecule is formed by two SPym ligand s, with S atoms in cis positions, and the N atom of the third SPym lig and. The S atom of this ligand, which is arranged nearly perpendicular to the equatorial plane, and the C(n-butyl) atom occupy the axial pos itions. Intermolecular distances shorter than the sum of the van der W aals radii were not found.
