2-Amino-5-methyl-pyridinium 3-amino-benzoate

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 inter-molecular N-H⋯O hydrogen bonds with the O atoms of the carboxyl-ate 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 inter-actions involving the benzene and pyridinium rings with a centroid-centroid distance of 3.7594 (8) Å.
