with the dirhodium complexes (η5-C5H5)2Rh2(μ-CO)(μ2-η2-CF3C2CF3) (I) and (η5:η5-C5H4CH2C5H4)Rh2(CO)2(μ2-η1:η1-CF3 C2CF3) (II) have been compared. The complexes (η5-C5H5)2Rh2(CO)η1-Ph2 P(CH2)nPPh2}(μ2-η1:η1-CF3C2CF3) (III, n = 1–4), which are formed from (I) and the appropriate bisphosphine, all have a trans arrangement of the carbonyl and bisphosphine ligands. When left in solution, the complex (III,
