Abstract: The molecule of the title compound, C16H16N2O4, adopts an E conformation about the azomethine C=N double bond. The dihedral angle formed by the benzene rings is 18.88 (9)°. The molecular conformation is stabilized by an intramolecular O-HN hydrogen bond, which forms an S(6) ring. In the crystal, the molecules are linked into chains parallel to  by N-HO hydrogen bonds. The chains are further connected into a three-dimensional network by - stacking interactions with centroid-centroid distances of 3.6538 (10) and 3.8995 (11) Å.
