On Chalcogenolates. 163. Reactions of Hydrazine with Carbon Disulfide. 2. Crystal Structure of Dipotassium 1,2-Hydrazine-bis (dithioformate) The title compound K₂S₂C? NH? NH? CS₂] ( 1 ) crystallizes with Z = 4 in the orthorhombic space group Pbna with cell dimensions a = 6.635(1), b = 10.825(2), c = 12.866(2) Å. The crystal structure has been determined from single crystal X-ray data measured at ?85 °C and refined to a conventional R of 0.034 for 969 independent reflections (R_w = 0.042). The S₂C? NH? NH? CS₂]^2? ions are linked together by hydrogen bridges N? H…?S. The K⁺ ions are surrounded by seven sulfur atoms in irregular coordination.
