Abstract:
The asymmetric unit of the title salt, C 5 H 8 N 3 + ·Cl − , comprises one half of the 2,6-diaminopyridinium cation (the other half being completed by the application of mirror symmetry) and one Cl − counter-anion, also located on the mirror plane. The amino N atom shows a significant pyramidalization, with a dihedral angle of 30.4 (14)° between the least-squares planes of the amino group and the non-H atoms of the 2,6-diaminopyridinium moiety. In the crystal, the cationic molecules and Cl − counter-anions are arranged in sheets parallel to (001) consisting of alternating polar and non-polar parts associated with the the Cl − anions, pyridinium and amino moieties, and the pyridine rings, respectively. N—H...Cl interactions within the polar part, as well as slipped π–π interactions in the non-polar part, help to establish the three-dimensional network.
