Abstract

In the title compound, C(5)H(8)N(3) (+)·C(7)H(5)O(2) (-), the pyridine N atom is protonated. The carboxyl-ate group of the benzoate anion is twisted away from the attached ring by 10.91 (9)°. In the crystal structure, N-H⋯O hydrogen bonds between 2,3-diamino-pyridinium cations and benzoate anions, and π-π inter-actions between the pyridinium rings [centroid-centroid distance = 3.6467 (9) Å] form a two-dimensional network parallel to (001). In the network, N-H⋯O hydrogen bonds form R(2) (2)(8) and R(2) (1)(7) ring motifs.
