Structural studies of group 5B-halide-dithio-ligand complexes. Part 3. Crystal structure of polymeric (NN-diethyldithiocarbamato)di-iodobismuth(III)

The crystal structure of the title compound, [Bi(S₂CNEt₂)l₂], has been determined by single-crystal X-ray diffraction methods at 295(1) K and refined by least-squares procedures to a conventional residual of 0.045 for 1 537 'observed' reflections. Crystals are monoclinic, space group P2₁/c, with a = 10.673(3), b = 15.001(3), c = 8.149(2) Å, β = 90.86(2)°, and Z = 4. The structure comprises an infinite linear polymeric array, successive bismuth atoms being bridged by a pair of iodine atoms and a ligand sulphur atom.
