Crystal structure of ammonium bis[(pyridin-2-yl)methyl]ammonium dichloride

Abstract

In the title molecular salt, C12H14N3+·NH4+·2Cl−, the central, secondary-amine, N atom is protonated. The bis[(pyridin-2-yl)methyl]ammonium and ammonium cations both lie across a twofold rotation axis. The dihedral angles between the planes of the pyridine rings is 68.43 (8)°. In the crystal, N—H...N and N—H...Cl hydrogen bonds link the components of the structure, forming a two-dimensional network parallel to (010). In addition, weak C—H...Cl hydrogen bonds exist within the two-dimensional network.
