Abstract: The title compound, C14H12N2O4·H2O, is stabilized in the solid state as a keto-amine tautomer, with two strong intramolecular N-HO, two intermolecular O-HO and three intermolecular C-HO hydrogen bonds. The organic molecule is approximately planar, with a dihedral angle of 1.90 (8)° between the two carbocyclic rings. The water molecules lie on a twofold symmetry axis.
