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

Two independent mol­ecules,1 and 2, with similar conformations comprise the asymmetric unit in the title compound, C(12)H(9)Br(2)NO. The major difference between the mol­ecules 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...

description Two independent mol­ecules,1 and 2, with similar conformations comprise the asymmetric unit in the title compound, C(12)H(9)Br(2)NO. The major difference between the mol­ecules 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 mol­ecules 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 mol­ecules, 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.
