Structural studies of Group 5B-halide-dithio-ligand complexes. Part 8. Crystal structure of N′N′-diethylthiocarbamoylpyridinium pentachloropyridinebismuthate(III)

The crystal structure of the title compound, [C₅H₅NCSNEt₂]₂[BiCl ₅(C₅H₅N)], 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 0.031 for 1 633 'observed' reflections. Crystals are orthorhombic, space group Pbcn, with a = 16.089(4), b = 14.852(4), c = 14.130(3) Å, and Z = 4. The anion lies on a crystallographic two-fold axis; Bi-N is 2.615(8) Å. The Bi-Cl distance trans to the Bi-N bond is shorter [2.637(3) Å] than the remainder [2.692(2), 2.700(3) Å]. The N-Bi-Cl (cis) angles are appreciably less than 90° [84.65(6), 84.91 (6°)].
