Plutonium trioxide is an inorganic compound of plutonium and oxygen with the chemical formula PuO3. This is a high-order oxide of plutonium where the metal is in the +6 oxidation state. The compound is less stable and less common than the common plutonium dioxide PuO2.
Theoretical calculations on molecular actinide trioxides predict that while molecular plutonium trioxide should attain the +6 oxidation state for plutonium, the molecular trioxides of the heavier actinides should be regarded as having the actinide in the +5 oxidation state
