2-Amino-5-methyl­pyridinium 2-amino­benzoate

In the 2-amino­benzoate anion of the title salt, C(6)H(9)N(2) (+)·C(7)H(6)NO(2) (−), an intra­molecular N—H⋯O hydrogen bond is observed. The dihedral angle between the ring and the CO(2) group is 8.41 (13)°. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl­ate O atoms via a pair of N—H⋯O hydrogen bonds, forming an R (2) (2)(8) ring motif. The ion pairs are further connected via N—H⋯O hydrogen bonds, resulting in a donor–donor–acceptor–acceptor (DDAA) array of quadruple hydrogen bonds. The crystal structure also features a weak N—H⋯O hydrogen bond and a C—H⋯π inter­action, resulting in a three-dimensional network.
