Abstract:
The title compound, C(24)H(12)BrCl(2)NO(4), was synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 2-chloro-benzoyl chloride. The crystal structure shows that each of the chloro-phenyl rings is inclined at about 60° to the naphthoquinone ring system. The two chloro-phenyl 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.
