The title compound, C 29 H 24 Br 2 , has crystallographic twofold rotation symmetry. The Br atom in the 2 position is disordered with the methyl group in the 6 position. The biphenyl bridge bond distance and the torsion angle between the rings are in good agreement with similar previously reported s
