The title compound, C14H11N3O5, is a Schiff base that adopts the enol-imine tautomeric form in the solid state. The dihedral angle between the aromatic rings is 37.4 (3)degrees and the dihedral angles between the nitro groups and their attached rings are 4.0 (6) and 46.2 (8)degrees. The molecular structure is stabilized by an intramolecular O-H center dot center dot center dot N hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked by C-H center dot center dot center dot O interactions, forming a two-dimensional network parallel to the bc plane.
