Abstract: In the crystal structure of the title salt, C6H8N+·C7H5O3-, the anions and cations are linked by classical N-H...O hydrogen bonds. The anions are connected by pairs of C-H...O hydrogen bonds into inversion dimers and further linked by classical O-H...O hydrogen bonds. Weak [pi]-[pi] interactions [centroid-centroid distances = 3.740 (3) and 3.855 (3) Å] also occur. The dihedral angle between the CO2- group and the benzene ring to which it is attached is 20.95 (8)°.
