3,3′,5,5′-Tetra­bromo-2,2′-bithio­phene

The title compound, C(8)H(2)Br(4)S(2), was prepared by bromination of 2,2′-bithio­phene with bromine. The mol­ecule is located on a crystallographic twofold rotation axis, thereby imposing equal geometry of the two thio­phene rings. Each five-membered ring is planar [maximum deviation 0.011 (9) Å] and the dihedral angle between the planes through the rings is 47.2 (4)°. The mol­ecules are arranged to minimize intramolecular contacts between the 3-3′ and 5-5′-bromine atoms.
