In the title molecule, C~16~H~11~Br~3~Cl~2~O~2~, the chain Br atoms are in __trans__ positions [BrβCβCβBr torsion angle is 179.0β (2)Β°]. The two benzene rings make a dihedral angle of 39.54β (15)Β°. The crystal packing is determined by van der Waals forces; some weak ΟβΟ interactions between the benzen
