Abstract
The crystal and molecular structure of the title compound has been determined using Patterson and Fourier techniques from diffractometer data. Crystals are monoclinic, space group P2 1/ c with a 10.805(7), b 20.292(15), c 10.804(8) Å, β 113.20(5)°, U 2177.37 Å 3. D m 1.85, D c 1.87 mg m −3 for Z = 8, with two independent molecules in the asymmetric unit. The structure has been refined using 1153 observed reflections to a final R = 0.075 and R′ = 0.080. The 2-pyridinecarboxylate ligand bridges adjacent tin atoms to give a polymeric structure consisting of chains which run parallel to the a axis. The pyridine ring is orientated to facilitate a close approach of the nitrogen atom to tin and the SnN distances of 2.468(20), 2.505(25) Å indicate the presence of a significant interaction. The resulting coordination about each tin atom is that of a distorted octahedron.
