[1,3-Bis(2,3,4,5,6-penta­fluoro­benz­yl)­benzimidazol-2-yl­idene]bromido(η⁴-cyclo­octa-1,5-diene)rhodium(I)

The title complex, [RhBr(C₈H₁₂)(C₂₁H₈N₂F₁₀)], 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 π–π stacking inter­actions.
