ABSTRACT In the title salt, C11H14N3O+·C7H5O3−, the phenyl ring of the cation is oriented at an angle of 67.0 (1)° with respect to the five-membered pyrazolone ring. The carboxylate plane of the anion is twisted out from the plane of the aromatic ring at an angle of 13.7 (3)°. In the crystal, the cations form hydrogen-bonded dimers with an R22(10) ring motif. The salicylate anion has an intramolecular O—H...O hydrogen bond.
