2-Amino-4-methyl­pyridinium 2-hy­droxy­benzoate

The asymmetric unit of the title mol­ecular salt, C(6)H(9)N(2) (+)·C(7)H(5)O(3) (−), contains two cations and two anions. Both the salicylate anions contain an intra­molecular O—H⋯O hydrogen bond, which generates an S(6) ring. Both the 2-amino-4-methyl­pyridine mol­ecules are protonated at their pyridine N atoms. In the crystal, both cations form two N—H⋯O hydrogen bonds to their adjacent anions, forming ion pairs. Further N—H⋯O links generate sheets lying parallel to the ab plane. In addition, weak C—H⋯O bonds and aromatic π–π stacking inter­actions [centroid–centroid distances = 3.5691 (9) and 3.6215 (9) Å] are observed between the cations and anions.
