In the title 1:1 adduct, C(6)H(4)N(2)·C(7)H(6)O(2), the carboxyl group and its attached phenyl ring are essentially coplanar, being twisted from each other by a dihedral angle of only 2.05 (3)°. In the crystal, the mol-ecules are connected via O-H⋯N and C-H⋯O hydrogen bonds, building an R(2) (2)(7) ring. Mol-ecules are further linked through π-π inter-actions [centroid-centroid distance of 3.8431 (8) and 3.9094 (8) Å], leading to a one-dimensional chain parallel to the b axis.
