Abstract
In the title compound, C17H14N2O2, the asymmetric unit comprises two molecules that are comformationally similar [the dihedral angles between the phenyl rings in each are 46.35 (2) and 48.04 (3)°], with the conformation stabilized by intramolecular O—H...N hydrogen bonds, which generate S(7) rings. In the crystal, inversion-related molecules are linked by pairs of weak C—H...O hydrogen bonds, forming dimers with an R22(16) graph-set motif. Weak inter-ring π–π stacking is observed in the structure, the shortest centroid-to-centroid distance being 3.7480 (13) Å.
