Complexation Study of UO2 2+ Ion with 18-Crown-6, Dicyclohexyl-18-crown-6 and Dibenzo-18-crown-6 in Binary Nitromethane-Acetonitrile Mixture by a Competitive NMR Technique Using 7 LI Nucleus as a Probe

Lithium-7NMRmeasurements were used to determine the stability of 1:1 Li+ complexes with 18-crown-6 (18C6), dicyclohexyl-18-crown-6 (DC18C6) and dibenzo-18-crown-6 (DB18C6) in various binary nitromethane-acetonitrile mixtures.Acompetitive 7LiNMR technique was also employed to probe the complexation of UO2 2+ ion with these crown ethers in the mixed solvents used. In all solvent mixtures, the stability of the resulting 1:1 complexes was found to decrease in the order DC18C6 > 18C6 > DB18C6. There is an inverse relationship between the complex stability and the amount of acetonitrile in the mixed solvents.
