Abstract
The crystal structure of the title compound has been determined by photographic X-ray methods by the heavy-atom method, and refined by block-diagonal least-squares to R 0·096 for 1203 independent reflections. Crystals are monoclinic, space group P21/a, a= 33·45(5), b= 8·47(2), c= 6·09(1)Å, β= 92·2(3)°, Z= 4. As in the other (α) form the cell contains discrete [Hg{CS(NH2)2}4]2+ and Cl– units, the mercury atom being in a highly distorted tetrahedron of sulphur atoms [Hg–S 2·51–2·62 Å, S–Hg–S 112–117°].Keywords
