  Abstract:  

The new (NH4)60{U3Ì{(MoVI)Mo5VIO21(H2O)6}12{Mo2VO4 (SO4}30].308H2O spherical cluster was synthesized as ammonium salt and investigated by means of elemental analyses, FT-IR, Raman, UV-Vis and EPR spectroscopy and by magnetic measurements. The results suggest the binding of uranium cations to the SO42- ligands and the quasi-cubic local symmetry around the uranium ions.

Keywords: Uranium (IV), metal clusters, IR, Raman, UV, Vis, RES spectroscopies, magnetic susceptibility.
