The title compound, C 20 H 13 Br 3 Cl 2 O 2 , arose unexpectedly as the product of a bromination reaction. The bromo substituents at the central C-C single bond are trans to each other ] and the dihedral angle between the mean planes of the aromatic ring systems is 38.28 (10) .
In the title compound, C 21 H 17 Br 3 O 3 , the two aromatic residues are almost coplanar with one another [dihedral angle = 9.92 (6) ]. The two Br atoms at the Csp 3 atoms are in a trans conformation. Related literature For background, see: Yathirajan et al. (2007).
