Abstract: The title compound, C21H18N2O3, exists in the E conformation with respect to the azomethane C=N double bond. The central benzene ring is almost coplanar with one of the substituent benzene rings [dihedral angle = 1.74 (5)°] and is approximately orthogonal to the other benzene ring of the mol­ecule [dihedral angle = 86.61 (7)°]. An intra­molecular O-H...N hydrogen bond occurs. The crystal packing is dominated by N-H...O hydrogen bonds, which lead to an infinite chain running parallel to [010].
