The title compound, C12H10N2O3, exists in the E conformation. The five-membered ring and the phenyl rings form dihedral angles of 36.73 (10) and 12.22 (10), respectively, with the central C(=O)N2C unit. The crystal packing is dominated by strong N - H?O and O - H?N hydrogen bonds. Together with weaker C - H?O interactions, these establish a three-dimensional supramolecular network.
