2-bis(diethylphosphino)ethane]) as ancillary ligands influences the stability and the reactivity of these complexes. The iron and osmium complexes are more stable than the ruthenium complexes that lose the dihydrogen ligand and coordinate the trifluoromethanesulfonate anion. The crystal structure of trans-[Ru(OTf)(CN)(dppe)2] is reported. The Ru–OTf bond is weak and so the triflate ligand can be displaced
