Coordination Chemistry Of The Bis(Trifluoromethylsulfonyl)Imide Anion: Molecular Interactions In Room Temperature Ionic Liquids

Room temperature ionic liquids composed of bis( trifluoromethylsulfonyl) imide anions and 1,3-ethylmethylimidazolium (EMI) cations are shown to stabilize monomeric ligand deficient transition metal complexes via four distinct binding modes: monodentate nitrogen or oxygen coordination and/or bidentate oxygen - oxygen' or nitrogen - oxygen coordination (eta(1) - N, eta(1) - O, eta(2) - O, O' and eta(2) - N,O).
