title: 2,9-Bis(trichloro-meth-yl)-1,10-phenanthroline.
abstract: The asymmetric unit of the title compound, C(14)H(6)Cl(6)N(2), contains two crystallographically independent mol-ecules, 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 mol-ecule, and 4.13 (8) and 4.10 (7)° in the other. In the crystal structure, mol-ecules are inter-linked by C-Cl⋯Cl inter-actions into sheets parallel to the ac plane. These sheets are stacked along the b axis in such a way that the mol-ecules are anti-parallel; they are further connected into a supra-molecular 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 inter-actions, with centroid-centroid distances in the range 3.5868 (9)-3.7844 (9) Å, are observed.
