Abstract
In the title compound, C24H12BrF2NO4, synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 4-fluorobenzoyl chloride, the two p-fluorophenyl rings are inclined at 73.9 (1) and 73.6 (1)° to the naphthoquinone ring system. The two imido carbonyl O atoms are anti to each other, while the fluorophenyl rings are located opposite each other, connected to the imide group in a funnel-like arrangement. This conformation allows the fluorine groups be oriented slightly away from each other. An examination of the packing shows a close intermolecular F⋯O contact of 2.982 (5) Å and a Br⋯O contact of 2.977 (4) Å. In addition, the molecules are linked by weak intermolecular C—H⋯O and C—H⋯F interactions.
