The mol-ecule of the title compound, C(14)H(10)N(2)O, displays a trans configuration with respect to the C=N double bond. The mol-ecule is roughly planar; the two aromatic rings make a dihedral angle of 9.3 (3)°. Such a planar conformation is induced by the strong intra-molecular O-H⋯N hydrogen bond between the imine and hydroxyl groups.
