(E)-N′-(2,4-Dichlorobenzylidene)-3-nitrobenzohydrazide

Abstract

The title compound, C14H9Cl2N3O3, was prepared by the reaction of 3-nitrobenzohydrazide with 2,4-dichlorobenzaldehyde. The molecule adopts an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 4.6 (2)°. In the crystal, the hydrazone molecules are linked through intermolecular N—H...O hydrogen bonds, forming chains along the c axis.
