Abstract

Vibrational spectra have been obtained for aqueous solution of UO2C104, Na3[UO2F5], [NH4]3[UO2F5], UO2F2, [Bu4N]2[UO2Cl4], UO2Cl2, UO(NO3)2, Rb [UO2(NO3)3], [Pr4N] [UO2(NO3)3], UO2(O2CCH3)2, [Pr4N] [UO2(O2CCH3)3] and UO2SO4 over a range of solution composition. The residual absorptions of H2O after water subtraction suggest that some water molecules are bound to [UO2]2+. There was no evidence of perchlorate coordination, but besides solvated [UO2]2+ ion formation of weak [UO2F]+ and [UO2Cl]+ complexes have been established. The four nitrate stretching features do not refer neither to bidentate nor to monodentate ligand, but both monodentate and bidentate linkage of acetate to uranyl were established for acetate complexes. The main species present in UO2SO4 solution can be ascribed to a monodentate sulphate. From uranyl frequencies force constants and UO bond distances were calculated for solvated complexes.
