trans-hexa-2,4-diene-, bis(methylenecyclopropane)-, or bis(acrylonitrile)-(η5-indenyl)rhodium. Reaction (room temperature) of hexafluorobut-2-yne with η5-indenyl(η5-isoprene)-rhodium leads to a cyclo-cotrimerisation reaction and the formation of η5-indenyll–2: 3–4η4-[6-endo-propen- 2-yl-1,2,3,4-tetrakis(trifluoromethyl)cyclohexa-l,3-diene]}rhodium, the structure in the solid state being established by a single-crystal
