2-Amino-5-methyl­pyridinium 3-amino­benzoate

In the title compound, C(6)H(9)N(2) (+)·C(7)H(6)NO(2) (−), the H atom of the N—H group and an H atom of the 2-amino group from the cation are involved in inter­molecular N—H⋯O hydrogen bonds with the O atoms of the carboxyl­ate group of the anion, forming an R (2) (2)(8) ring motif. These ring motifs are, in turn, connected by further N—H⋯O hydrogen bonds, forming a two-dimensional network. The crystal structure is further stabilized by π⋯π stacking inter­actions involving the benzene and pyridinium rings with a centroid–centroid distance of 3.7594 (8) Å.
