چکیده
In the title compound, C(5)H(8)N(3) (+)·C(7)H(5)O(2) (-)·C(7)H(6)O(2), the carboxyl and carboxyl-ate groups are twisted away from their attached benzene rings by 10.75 (7) and 20.33 (6)°, respectively. In the crystal structure, the 2,3-diamino-pyridinium cations, benzoate anions and benzoic acid mol-ecules are linked into a two-dimensional network parallel to (001) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds and π-π inter-actions between the pyridinium rings [centroid-centroid distance = 3.4981 (7) Å].
