Abstract:

Products of anodic dissolution of uranium metal and the cathodic reduction of uranium(IV) ions in a molten eutectic mixture of lithium and potassium chlorides are studied at 450 degrees C using x-ray absorption spectroscopy. It is shown that UCl63- \_ ions form in the melt as a result of the metal's anodic dissolution, and the metal-ligand distance in the complex ion is 0.284 nm. No complex ions of another configuration are found to form. Cathodic reduction of the UCl(6)(2-)ions also yields the UCl63- ions, with longer U-Cl bonds.
