Plutonyl ions

Balance the equation for the reaction between permanganate, MnO faqj, and plutonium(III), Pu+Yagj, to form manganous, Mn+2(ag), and plutonyl ion, PuO faq), in acid solution. 

Measurements on single crystals of lower symmetry doped with NpO or PuOl" " should remove this uncertainty but no such experiment has been performed so far. However, the distinction between configurations (a) and (b) has been possible in an electron paramagnetic resonance study at 20 K on a single uniaxial crystal of RbU02(N03)3 doped with plutonyl ions. This study conclusively showed that the ground state is H4 with gy = 5.4 and g = 0 28). 

Low coordination numbers also occur with ions of high valency such as the uranyl ion [U02]2+ and the corresponding neptunyl and plutonyl ions here there is also no question of an ionic bond. 

VI states occurs in water. Once the uranyl, neptunyl, and plutonyl ions are formed, the only practical way to remove the coordinated oxygen atoms is by reduction to the IV state. Although uranyl nitrate can be obtained as an anhydrous compound, in this form it is coordinatively unsaturated, and it is usually encountered as the hexahydrate or coordinated to equivalent ligands.
