(2-Hydroxyethyl)hydrazinium(2+) Dichloride

Abstract

The crystal structure of the title compound, C<inf>2</inf>H <inf>10</inf>N<inf>2</inf>O2+·2Cl-, is built up from one 2-hydroxyethylhydrazinium(2+) cation and two Cl- anions. The molecular structure is stabilized by O-H⋯Cl and N-H⋯Cl hydrogen bonds. The crystal structure is stabilized by one N-H⋯O and three N-H⋯Cl interactions, and the three-dimensional network of hydrogen bonds stabilizes the crystal packing. All five hydrazinium H atoms are involved in hydrogen bonds to Cl- anions. The Cl⋯H contact distances range from 2.122 (15) to 2.809 (14) Å. © 2005 International Union of Crystallography.
