Synthesis and crystal structure of polymeric triphenyltin(IV) 4-pyridinecarboxylate

A crystal structure determination of the title compound reveals that it has a one-dimensional polymeric structure co-crystallized with molecules of th e crystallization solvent, toluene, in 1:1 ratio in the crystal lattice. Ea ch of the Sn atoms exists in a distorted trigonal bipyramidal geometry with the axial positions occupied by the O atom of the carboxylate group and th e N atom of the pyridyl ring of the neighbouring molecule. The axial N'-Sn- O connection makes an angle approaching linearity (175.5(1)degrees).
