In the title compound [systematic name: 2,3-dibromo-3-(2-bromophenyl)-1-(5-oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-yl)propan-1-one], C17H11Br3N2O3, the oxadiazole ring is essentially planar, with a maximum deviation of 0.003 (1) Å. The –CHBr–CHBr– chain and bromophenyl ring are disordered over two sets of sites with a refined occupany ratio of 0.756 (5):0.244 (5). The central oxadiazole ring makes dihedral angles of 54.07 (11) and 13.76 (18)° with the attached phenyl and the major component of the bromo-substituted benzene rings, respectively. The dihedral angle between the major and minor components of the bromophenyl rings is 13.4 (5)°. In the crystal structure, molecules are connected by C—H...O hydrogen bonds, forming [010] ribbons.
