Abstract

The title compound (OctaInd), C(18)H(12)Br(8), is a commercial brominated flame retardant (BFR). In the mol-ecule, the five-membered ring has a slight envelope conformation, with a deviation of 0.317 (9) Å for the flap C atom from four essentially planar C atoms. The dihedral angle between the two benzene rings is 74.00 (16) Å.
