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), [LiUO₂(μ₂-(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.
