The mol-ecule of the title compound, C(16)H(16)N(2)O(4), exists in the E configuration with respect to the central C=N double bond. The dihedral angle between the two benzene rings is 2.17 (9) Å. In the crystal, mol-ecules are linked via O-H⋯N hydrogen bonds into chains that propagate along the b-axis direction. There is also π-π stacking of inversion-related mol-ecules, with inter-planar spacings of 3.479 (5) Å and ring centroid-centroid distances of 3.876 (4) Å. ...[more]
