1-(6,8-Dibromo-2-methyl-quinolin-3-yl)ethanone

Abstract

Two independent mol-ecules,1 and 2, with similar conformations comprise the asymmetric unit in the title compound, C 12H 9Br 2NO. The major difference between the mol-ecules relates to the relative orientation of the ketone-methyl groups [the C-C-C-C torsion angles are -1.7 (6) and -16.8 (6)° for mol-ecules 1 and 2, respectively]; in each case, the ketone O atom is directed towards the ring-bound methyl group. The crystal packing comprises layers of mol-ecules, sustained by C-H⋯O and π-π {ring centroid(C 6) of molecule 2 with NC 5 of molecule 1 [3.584 (3) Å] and NC 5 of molecule 2 [3.615 (3) Å]} interactions. C-H⋯Br contacts also occur.
