Abstract

The title complex, [RhBr(C<inf>8</inf>H<inf>12</inf>)(C<inf>24</inf>H <inf>19</inf>F<inf>5</inf>N<inf>2</inf>)], has a distorted pseudo-square-planar geometry. The Rh - C bond distance between the N-heterocyclic ligand and the metal atom is 2.022(3). The angle between the carbene heterocycle and the coordination plane is 75.60(11)°. It is shown that the average Rh - C(cyclooctadiene) distance is linearly dependent on the Rh - C(imidazole) distance in this type of compound. The crystal structure contains one intramolecular and two intermolecular types of C - H⋯F interactions, as well as one type of π-π stacking interaction. © 2006 International Union of Crystallography.
