Abstract: The title compound, C₁₂H₁₀N₂O₆, was synthesized via a Knoevenagel condensation and crystallized from ethanol. In the crystal, strong classical intermolecular O-HO hydrogen bonds and weak C-HN contacts link the molecules into ribbons extending along [010]. Intramolecular O-HO and C-HN contacts support the planar conformation of the molecules (mean deivation 0.0270 Å).
