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).
