The asymmetric unit of the title compound, C 14 H 6 Cl 6 N 2 , contains two crystallographically independent mol­ecules, each of which is slightly twisted from planarity. The dihedral angles between the central ring and the two outer rings are 3.81 (7) and 4.30 (7)° in one mol­ecule, and 4.13 (8) and 4.10 (7)° in the other. In the crystal structure, mol­ecules are inter­linked by C—Cl⋯Cl inter­actions into sheets parallel to the  ac  plane. These sheets are stacked along the  b  axis in such a way that the mol­ecules are anti­parallel; they are further connected into a supra­molecular network. There are no classical hydrogen bonds. C⋯Cl [3.637 (2) Å], Cl⋯Cl [3.5639 (5)–3.6807 (8) Å] and Cl⋯N [3.3802 (15)–3.4093 (15) Å] short contacts and π–π inter­actions, with centroid–centroid distances in the range 3.5868 (9)–3.7844 (9) Å, are observed.
