Plutonyl

The plutonyl ion is an oxycation of plutonium in the oxidation state +6, with the chemical formula PuO2+
2. It is isostructural with the uranyl ion, compared to which it has a slightly shorter M–O bond. It is easily reduced to plutonium(III). The plutonyl ion forms many complexes, particularly with ligands that have oxygen donor atoms. Complexes of the plutonyl ion are important in nuclear fuel reprocessing.
