Abstract: The molecule of the title compound, C15H14N4O3, is completed by the application of crystallographic twofold symmetry, with the carbonyl group lying on the rotation axis. The molecule is close to planar: the greatest deviation of a torsion angle from 0° is 7.3 (2)° about the bond linking the phenol ring to the rest of the molecule. An intramolecular O-HN(imine) hydrogen bond is formed in each half of the molecule. The carbonyl O atom is anti with respect to the amine H atoms and this allows for the formation of N-HO(hydroxyl) hydrogen bonds in the crystal, which results in supramolecular layers lying parallel to (100).
