Crystal structure of N (1)-benzyl-N (1),N (2),N (2)-tri-methyl-ethane-1,2-diaminium dichloride.

In the title mol-ecular salt, C12H22N2 (2+)·2Cl(-), which was obtained as a by-product in the attempted synthesis of a mercury derivative, the conformation of the N-C-C-N bond in the cation is anti [torsion angle = 175.1†(10)°]. In the crystal, the cations are linked to the anions by N-H⋯Cl hydrogen bonds, generating ion-triplets. These are linked by numerous weak C-H⋯Cl inter-actions, generating a three-dimensional network. The structure was refined as an inversion twin.
