A convenient preparation and full characterization, including a crystal structure, of green, crystalline [Co(NH3)6][Co(CO3)3] is reported. This salt can be treated at 0°C with aqueous solutions of HClO4, HNO3 or CF3SO3H to give CO2(g), the corresponding insoluble salt of Co(NH3)63+ and aqueous Co(OH2)63+. This reaction provides ready access to solutions of Co(OH2)63+ in a wide range of concentrations and acidities.

Methods of depolymerization of polymeric Pu(IV) in 0.5-3 M HNO3 in the presence of reductants [hydroquinone, H2O2, hydroxylamine, U(IV)] and oxidants [KMnO4, H2O2 + Fe(NO3)3, Na2S2O8 + catalysts, Co(III)] were studied. The ratios of various oxidation states and complex species of plutonium in such systems were determined by electronic absorption spectroscopy. A mechanism of depolymerization of Pu(IV) by sodium persulfate in 0.5-3 M HNO3 in the presence of Co(II) salts was proposed. The stepwise stability constant of the PuO2SO4 complexes K1 was estimated.
