The asymmetric unit of the title compound, C14H8N2O8·2C3H7NO or L·2DMF (DMF = N,N-dimethylformamide), contains one here half of the centrosymmetric molecule L and one solvent molecule, which is disordered between two orientations in a 0.555 (4):0.445 (4) ratio.

Intermolecular O—H.O hydrogen bonds link one L and two DMF molecules into read more a centrosymmetric hydrogen-bonded cluster.The crystal packing is further stabilized by weak intermolecular C—H.

O hydrogen bonds.
