Abstract: The molecule of the title compound, C14H11N3O4, assumes an E conformation about the C=N double bond. The benzene rings form a dihedral angle of 3.9 (2)°. The crystal structure is stabilized by N-H...O, O-H...N, O-H...O and C-H...O hydrogen bonds, forming layers parallel to (101). In addition, intralayer [pi]-[pi] stacking interactions [centroid-centroid distance = 3.635 (2) Å] are observed.
