title: 2,4-Dichloro-quinoline.
abstract: The asymmetric unit of the title compound, C(9)H(5)Cl(2)N, consists of two crystallographically independent mol-ecules. In both mol-ecules the quinoline ring system is essentially planar [maximum deviations from the best plane of 0.0232 (13) 0.0089 (15) Å]. The angle between these planes is 22.40 (3)°. Conformers A and B are arranged face-to-face along the c axis, forming alternating pairs in the order AABB. The inter-planar distances AA, AB and BB are 3.3166 (11), 3.2771 (11) and 3.3935 (11) Å, respectively. The crystal packing is stabilized by weak C-H⋯Cl and C-H⋯N inter-actions.
