Abstract: The molecule of the centrosymmetric title compound, C₁₈H₂₀N₂O₆, assumes an E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. Intramolecular O-HO and O-HN bonds are found between the hydroxyl groups and adjacent O (or N) atoms. In the crystal structure, intermolecular O-HO bonds link each molecule to two others, forming a layered network.
