title: 9,9'-Dibromo-9,9'-bifluorene.
abstract: 9,9'-Dibromo-9,9'-bifluorene, C(26)H(16)Br(2), has a gauche conformation about the connecting C-C bond [the Br-C-C-Br torsion angle is 59.39 (16)°]. The crystal structure is sustained mainly by an inter-molecular C-Br⋯π inter-action [3.299 (2) and 3.369 (2) Å] towards the bifluorene aromatic-ring-connecting C-C bond and a weak C-H⋯π inter-action (2.86 and 2.99 Å) between the two aromatic rings.
