The title compound, C(14)H(10)Cl(2)N(2)O, was prepared from the reaction of 2-chloro-benzaldehyde with 3-chloro-benzo-hydrazide in methanol. The mol-ecule adopts an E configuration about the methyl-idene unit and the two aromatic rings form a dihedral angle of 13.8 (2)°. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming chains along the c axis.
