Redetermination of hydrogenhydrazinium dichloride

R. Kruszynski and A. Trzesowska

Abstract: The crystal structure of the title compound, N₂H₆²⁺·2Cl^-, previously determined by photographic methods [Wyckoff (1923). Am. J. Sci. 5, 15-22; Donohue & Lipscomb (1947). J. Chem. Phys. 15, 115-119], has been redetermined from single-crystal data. The N and Cl atoms are located on threefold rotation axes, whereas the H atom lies in a general position. The [H₆N₂]²⁺ cations and the Cl^- anions are connected via N-HCl hydrogen bonds forming a three-dimensional net, whereby R₆³(14) rings are generated.
