Crystal structure of N1-benzyl-N1,N2,N2-trimethylethane-1,2-diaminium dichloride

Abstract

In the title molecular salt, C12H22N22+·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 interactions, generating a three-dimensional network. The structure was refined as an inversion twin.
