Abstract

Trimethylglycine and betainium class ionic liquids were employed in synthesizing six uranyl-betaine coordination complexes: [(μ2-(CH3)N2C3H3(CH2COO))2 (UO2(Cl)((CH3)N2C3H3(CH2COO)))2] 2[N(SO2CF3)2] (1), [K][UO2(Cl)3((CH3)3NCH2COO)] (2), [(CH3)3NCH2COOH][UO2(Cl)3((CH3)3NCH2COO)]?H2O (3), [LiUO22-(CH3)3NCH2COO)4] 3[N(SO2CF3)2] (4) {(μ2-(CH3)3NCH2COO)UO2(NO3)2((CH3)3NCH2COO)}2 UO2(NO3)2, UO2(NO3)2(H2O)2?H2O (5), and UO2(Cl)2(H2O)(μ2-(CH3)3NCH2COO) (6). These complexes expound upon the variability of monocarboxyl-functionalized uranyl coordination complexes, providing an enhanced framework for investigations into the structural chemistry of analogous actinyl systems.
