title: 2-[(2-hydroxy-4-nitrophenyl)aminomethylene]cyclohexa-3,5-dien-1(2H)-one.
abstract: The title compound, C(13)H(10)N(2)O(4), adopts the keto-amine tautomeric form and displays an intramolecular N-H...O [N...O = 2.579 (2) A] and three intermolecular O-H...O [O...O = 2.561 (2) A] and C-H...O [C...O = 3.274 (2) and 3.318 (2) A] 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) degrees.
