(E)-N′-(3,4-Dihydroxybenzylidene)-4-nitrobenzohydrazide
Abstract
In the title Schiff base compound, C14H11N3O5, the dihedral angle between the two benzene rings is 1.6 (1)°. The molecule displays an E configuration about the C=N bond. An intramolecular O—H...O hydrogen bond is observed. In the crystal, molecules are linked into layers parallel to (101) by O—H...O, N—H...O and C—H...O hydrogen bonds. One of the hydroxyl groups is disordered over two positions, with occupancies of 0.643 (5) and 0.357 (5).
