The spectroscopic and electrochemical behavior of the complex of tetraalkylurea ligands with uranyl(VI) and europium(III) in ionic liquid 1-butyl-3-methylimidazolium bis(tri-fluoromethylsulfonyl)imide ([Bmim][NTf2]) was studied. As the steric hindrance of the substituent increases, the number of ligands in the [UO2(L)n]2+ complex decreases, however, Eu(III) maintains 8-coordinated complexes [Eu(L)8]3+. The effect of urea ligands on the redox potential of Eu(III) is significantly greater than that of UO22+. Tetrabutylurea can better stabilize the low-valence Eu(II) and improve the redox reversibility of UO22+.
