Sumario:In the title molecular salt, C(7)H(11)N(2) (+)·C(13)H(9)N(2)O(3) (−), the dihedral angle between the benzene rings in the anion is 35.14 (8)°. In the crystal, centrosymmetrically related anions associate via hydrox­yl–carboxyl­ate O—H⋯O hydrogen bonds, resulting in a 24-membered {⋯OC(3)N(2)C(4)OH}(2) synthon. The cations are associated with this dimeric unit via pyridinium–carboxyl­ate N—H⋯O hydrogen bonds. Weak C—H⋯O links further consolidate the packing, generating layers.
