title = "Apples to apples: A comparison of lanthanide {\ss}-diketonate complexes in molecular solvents and an ionic liquid",
abstract = "The structure, stoichiometry, and chemical equilibria governing the complexes formed by lanthanide ions (Ln3+) and the extradant 2-thenoyltrifluoroacetone (Htta) were studied in a biphasic system composed of aqueous 1 M NaClO4 and the hydrophobic ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. Two different Ln-tta complexes were observed in the ionic liquid phase depending on the solution conditions. A neutral Ln(tta)3 complex predominates at low tta- concentration, while the anionic complex Ln(Wa)4 - is extracted into the ionic liquid phase by an anion exchange mechanism at higher tta- concentrations. Both complexes have been observed in molecular solvents previously, allowing a direct and quantitative comparison of the ionic liquid based system to conventional liquid-liquid extraction systems.",
