The title compound, C20H12Br2N2, was prepared by the reaction of 1-(3-bromophenyl)-2-(4-bromophenyl)ethane-1,2-dione with o-phenylenediamine in refluxing ethanol. In the molecule, all bond lengths and angles are within normal ranges. The dihedral angle between the two benzene rings is 34.89 (1)°. The dihedral angles between the benzene rings and the quinoxaline system are 57.23 (1) and 36.75 (1)°. The crystal packing is stabilized by van der Waals forces.
