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 OBr and ClCl contacts of 2.947 (2) and 3.346 (1) Å, respectively. In addition, the molecules are linked by weak intermolecular C-HO and C-HCl interactions.
