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

Abstract

The crystal structure of the title compound, [C₅H₅NCSNEt₂]₂[BiCl₅(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°)].
