In the crystal of the title compound, C16H9BrN2O4·0.5C6H6, the mol-ecules stack in a centrosymmetric unit cell in a 2:1 stoichiometry with co-crystallized benzene solvent mol-ecules and inter-act via various weak inter-actions. This induces a geometry different from that predicted by theory, and is unique among the hemibi-quinones heretofore reported.
