2-Amino-5-methyl­pyridinium 4-methyl­benzoate

The 4-methyl­benzoate anion of the title salt, C(6)H(9)N(2) (+)·C(8)H(7)O(2) (−), is nearly planar, with a dihedral angle of 6.26 (10)° between the benzene ring and the carboxyl­ate group. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl­ate O atoms of the anion via a pair of N—H⋯O hydrogen bonds with an R (2) (2)(8) ring motif, forming an approximately planar ion pair with a dihedral angle of 9.63 (4)° between the pyridinium and benzene rings. The ion pairs are further connected via N—H⋯O and weak C—H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.
