The components of the title compound, C8H6Br6 and C8H4Br6, are hexa- and tetrabromopentalene derivatives, which were obtained by the treatment of hexahydropentalene with a tenfold excess of bromine. The asymmetric unit consists of two half-mol-ecules. Crystallographic centres of symmetry are located at the mid-points of the central C=C and C-C bonds. The repulsive inter-actions between the Br atoms may affect the mol-ecular geometry.
