Abstract

In the title compound, C(17)H(14)N(2)O(2), the asymmetric unit comprises two mol-ecules 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 intra-molecular O-H⋯N hydrogen bonds, which generate S(7) rings. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds, forming dimers with an R(2) (2)(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.
