title: Crystal structure of ammonium bis-[(pyridin-2-yl)meth-yl]ammonium dichloride.
abstract: In the title molecular salt, C12H14N3 (+)·NH4 (+)·2Cl(-), the central, secondary-amine, N atom is protonated. The bis-[(pyridin-2-yl)meth-yl]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.
