3-Chloro-N'-(2,4-dichloro-benzyl-idene)benzohydrazide.

ABSTRACT: The title compound, C(14)H(9)Cl(3)N(2)O, adopts an E configuration about the methyl-idene unit and the two aromatic rings form a dihedral angle of 6.6?(2)°. In the crystal, mol-ecules are linked via N-H?O hydrogen bonds, forming C(4) chains propagating in [001]. C-H?O inter-actions reinforce the chains.
