Abstract: | The title compound, C13H10N2O4, adopts the keto–amine tautomeric form and displays an intramolecular N—H⋯O N⋯O = 2.579 (2) Å] and three intermolecular O—H⋯O O⋯O = 2.561 (2) Å] and C—H⋯O C⋯O = 3.274 (2) and 3.318 (2) Å] hydrogen bonds. The keto–amine structure is favoured by through‐molecule conjugation between the hydroxy O atom and imine N atom. The dihedral angle between the planes of the two aromatic rings is 10.79 (4)°. |
