2-Amino-5-methyl­pyridinium 2-hy­droxy­benzoate

In the title compound, C(6)H(9)N(2) (+)·C(7)H(5)O(3) (−), the protonated 2-amino-5-methyl­pyridinium cation and the 2-hy­droxy­benzoate anion are both essentially planar, with maximum deviations of 0.026 (2) and 0.034 (1) Å, respectively. The anion is stabilized by an intra­molecular O—H⋯O hydrogen bond, which forms an S(6) ring motif. In the solid state, the anions are linked to the cations via pairs of inter­molecular N—H⋯O hydrogen bonds forming R (2) (2)(8) ring motifs. The crystal structure is further stabilized by N—H⋯O and C—H⋯O inter­actions which link the mol­ecules into chains along [010]. A π–π stacking inter­action [centroid–centroid-distance = 3.740 (2) Å] is also observed.
