In the crystal structure of the title salt, C6H8N+·C7H5O3−, the anions and cations are linked by classical N—HO hydrogen bonds. The anions are connected by pairs of C—HO hydrogen bonds into inversion dimers and further linked by classical O—HO hydrogen bonds. Weak π–π 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)°.

In the title salt, C8H12N+·C7H5O3−, the cation is disordered over two orientations with site occupancies of 0.565 (7) and 0.435 (7). In the anion, the carboxylate group makes the dihedral angle of 4.19 (18)° with the benzene ring. In the crystal, the ions are connected by N—HO and O—HO hydrogen bonds, forming a three-dimensional network.

The asymmetric unit of the title compound, C6H5N3·C7H6O3, comprises independent benzotriazole and 4-hydroxybenzoic acid molecules. The dihedral angle between the benzene ring and the benzotriazole ring system is 15.18 (7)°. The mean plane of the carboxyl group is twisted at an angle of 18.55 (1)° with respect to the benzene ring. The crystal structure is stabilized by weak intermolecular N—HN, O—HN, O—HO and C—HO interactions, forming a three-dimensional network.
