Abstract
The title compound, C24H12BrCl2NO4, was synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 2-chlorobenzoyl chloride. The crystal structure shows that each of the chlorophenyl rings is inclined at about 60° to the naphthoquinone ring system. The two chlorophenyl rings adopt a conformation that ensures that chlorine substituents are anti so as to reduce electronic repulsion. An examination of the packing shows close O⋯Br and Cl⋯Cl contacts of 2.947 (2) and 3.346 (1) Å, respectively. In addition, the molecules are linked by weak intermolecular C—H⋯O and C—H⋯Cl interactions.
