Abstract

In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), an intra-molecular O-H⋯O hydrogen bond occurs within the anion, thereby generating an S(7) ring, which may correlate with the fact that both the carb-oxy-lic acid and carboxyl-ate groups are almost coplanar with their attached rings [dihedral angles = 2.9 (3) and 5.2 (3)°, respectively]. In the crystal, each cation is linked to its adjacent anion by two N-H⋯O hydrogen bonds; the dihedral angle between the pyridine and benzene rings is 2.22 (10)°. The ion pairs are linked by further N-H⋯O inter-actions.
