ABSTRACT In the title salt, C(11)H(14)N(3)O(+)·C(7)H(5)O(3) (-), the phenyl ring of the cation is oriented at an angle of 67.0 (1)° with respect to the five-membered pyrazolone ring. The carboxyl-ate 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 R(2) (2)(10) ring motif. The salicylate anion has an intra-molecular O-H⋯O hydrogen bond.
