4-Amino­pyridinium 2-hy­droxy­benzoate

In the salicylate anion of the title salt, C(5)H(7)N(2) (+)·C(7)H(5)O(3) (−), an intra­molecular O—H⋯O hydrogen bond generating an S(6) ring motif is observed. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to the ab plane by N—H⋯O and C—H⋯O hydrogen bonds. The network contains R (2) (2)(7) and R (1) (2)(4) ring motifs. Weak π–π inter­actions between the benzene and pyridinium rings [centroid–centroid distance = 3.688 (1) Å] are also observed.
