2,3-Diaminopyridinium benzoate

K. Balasubramani and H.-K. Fun

Abstract: In the title compound, C₅H₈N₃⁺·C₇H₅O₂^-, the pyridine N atom is protonated. The carboxylate group of the benzoate anion is twisted away from the attached ring by 10.91 (9)°. In the crystal structure, N-HO hydrogen bonds between 2,3-diaminopyridinium cations and benzoate anions, and - interactions between the pyridinium rings [centroid-centroid distance = 3.6467 (9) Å] form a two-dimensional network parallel to (001). In the network, N-HO hydrogen bonds form R₂²(8) and R₂¹(7) ring motifs.
