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 [001] by N—HO hydrogen bonds. The chains are further connected into a three-dimensional network by π–π stacking interactions with centroid–centroid distances of 3.6538 (10) and 3.8995 (11) Å.

The title compound, C15H14N2O4 adopts an E conformation about the azomethine double bond. Intramolecular N—HO and O—HN hydrogen bonds generate S(6) rings and help to establish the molecular conformation. The dihedral angle between the benzene rings is 17.84 (10)°. In the crystal, molecules are linked by O—HO and C—HO hydrogen bonds into a two-dimensional network with a herring-bone pattern arranged parallel to the bc plane.
