(m-Phenylenedimethylene)diammonium dichloride

H. Cheng and H. Li

Abstract: The asymmetric unit of the title compound, C₈H₁₄N₂²⁺·2Cl^-, contains one and a half of the dications and three chloride anions. The half molecule is completed by crystallographic twofold symmetry with two C atoms lying on the rotation axis. The two ammonium groups in each cation adopt a trans conformation with respect ot the benzene ring. The ammonium groups and chloride anions are involved in the formation of a three-dimensional N-HCl hydrogen-bonding network, which stabilizes the crystal packing.
