N-(3-Bromo-1,4-dioxo-1,4-dihydro-2-naphth­yl)-4-fluoro-N-(4-fluoro­benzo­yl)benzamide

摘要

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.
