摘要：

The interaction of Ln(III) and UO2(2+) ions with a strong donor, dimethylsulphoxide (DMSO) and a moderately coordinating anion, perchlorate, is investigated in anhydrous acetonitrile by means of Fourier transform IR and Raman measurements. The coordination mode of the ligands is determined, as well as the average coordination numbers. Perchlorate is bonded in the inner coordination sphere in both a monodentate and a bidentate fashion. Changes in coordination numbers of up to 2 are observed both within the lanthanide series and with the solvent composition, for instance upon the addition of DMSO. The data are interpreted in terms of equilibra between differently coordinated species. Whenever possible, apparent formation constants are calculated for the various solvates.
