Abstract: The title compound, C16H15NO4, exists as a zwitterion in the solid state, with the carboxylic acid group being deprotonated and the imine N atom being protonated. The molecule adopts an E configuration about the C=N double bond. The dihedral angle between the benzene rings is 46.34 (4)°. An intramolecular N-HO hydrogen bond generates an S(6) ring motif. In the crystal, adjacent molecules are connected by intermolecular O-HO and C-HO hydrogen bonds, forming supramolecular ribbons along the a axis.
