(m-Phenyl­enedimethyl­ene)diammonium dichloride

The asymmetric unit of the title compound, C(8)H(14)N(2) (2+)·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—H⋯Cl hydrogen-bonding network, which stabilizes the crystal packing.
