Abstract: The title compound, C₂₂H₂₉N₃O₅, is approximately planar with the aromatic rings in a trans configuration with respect to the azo double bond. The eneamine portion of the molecule exists as the keto-amine tautomer, stabilized by a strong intramolecular N-HO hydrogen bond. Intramolecular N-HO and O-HO and intermolecular O-HO and C-HO interactions influence the conformation of the molecules and the crystal packing.
