N′-(4-Hydroxybenzylidene)-4-nitrobenzohydrazide

Abstract

The title compound, C14H11N3O4, was prepared by the reaction of 4-nitrobenzohydrazide with 4-hydroxybenzaldehyde. The whole molecule of the compound is approximately planar, with a mean deviation from the least-squares plane through all the non-H atoms of 0.050 (2) Å; the dihedral angle between the two benzene rings is 2.0 (2)°. In the crystal, the benzohydrazide molecules are linked through intermolecular O—H...O and N—H...O hydrogen bonds, forming layers in the bc plane.
