In the title molecular salt, C(13)H(15)N(2) (+)·C(8)H(5)O(4) (-), the 2-carb-oxy-benzoate anions are joined into a chain along [010] by strong O-H⋯O hydrogen bonds, with the H atoms disordered about the inter-vening centres of inversion. The presence of N-H⋯O hydrogen bonds between cations generates an additional chain along [010] and parallel to that of the anions. The chains are assembled into a three-dimensional framework via weak C-H⋯O inter-chain inter-actions. In the cation, thee dihedral angle between the pyridine rings is 48.91 (4)°.
