In the mol-ecular structure of the title compound, C(13)H(9)Cl(2)NO, the amide N-C=O plane makes dihedral angles of 31.53 (8) and 36.23 (8)°, respectively, with the 4-chloro- and 2-chloro-phenyl rings. The dihedral angle between the two benzene rings is 6.25 (8)°. The mol-ecules are stacked in columns along the b axis through inter-molecular N-H⋯O hydrogen bonds. The columns are further connected by weak C-H⋯O hydrogen bonds. The compound is not isomorphous with the fluoro analogue.
