title: 2-Amino-4-methyl-pyridinium 2-carb-oxy-benzoate.
abstract: In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), the anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, the cations and anions are linked to form extended chains along [001] by O-H⋯O and N-H⋯O hydrogen bonds. Adjacent chains are crosslinked via C-H⋯O inter-actions into sheets lying parallel to (100).
