The title complex, [RhBr(C(8)H(12))(C(21)H(8)N(2)F(10))], has a slightly distorted pseudo-square-planar geometry. The whole molecule has an approximate mirror symmetry, with the mirror plane passing through the mid-points of the two alkene bonds of the cycloocta-1,5-diene (COD) ligand. The average Rh-C(COD) distance is inversely related to the magnitude of the Rh-C(benzimidazole) distance in this type of compound. The molecules are stacked in columns running along the a axis. The crystal structure contains two types of intermolecular C-H...F interactions, as well as two weak pi-pi stacking interactions.
