title: 3,3',5,5'-Tetra-bromo-2,2'-bithio-phene.
abstract: The title compound, C(8)H(2)Br(4)S(2), was prepared by bromination of 2,2'-bithio-phene with bromine. The mol-ecule is located on a crystallographic twofold rotation axis, thereby imposing equal geometry of the two thio-phene 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 mol-ecules are arranged to minimize intramolecular contacts between the 3-3' and 5-5'-bromine atoms.
