3,3',5,5'-Tetrabromo-2,2'-bithiophene

H. Li and L. Li

Abstract: The title compound, C₈H₂Br₄S₂, 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.
