Abstract
Thermodynamic data for the formation of cesium complexes with 18-crown-6 (18C6, L) [Cs(18C6)]+ in N-butyl-4-methyl- pyridinium tetrafluoroborate, 1-butyl-3-methylimidazolium tetrafluoroborate and 1-butyl-3-methylimidazolium dicyanamide, measured using 133Cs NMR spectroscopy at 23–50 ̊C, revealed that the stability of cesium complex in ionic liquids is affected by the nature of both cation and anion of room temperature ionic liquid and is in the range between the values found for water and DMF.
