N′-[(E)-4-Chlorobenzylidene]-2-(2,3-dimethylanilino)benzohydrazide

Abstract

In the title compound, C22H20ClN3O, the dihedral angle between the planes of the chlorophenyl and dimethylphenyl rings is 66.50 (9)°. These rings make dihedral angles 47.79 (8) and 69.24 (9)°, respectively, with the central benzene ring. In the crystal, molecules are linked into a three-dimensional supramolecular network by N—H...O, C—H...O hydrogen bonds and weak C—H...π interactions.
