Plutonium(IV) iodate is an inorganic compound with the chemical formula Pu(IO3)4, it is a salt which decomposes into plutonium(IV) oxide above 540 °C.[3] It can be generated in the reaction of plutonium(IV) nitrate and iodic acid, but this method cannot obtain a pure product;[3] Another preparation method is the reaction of plutonium(IV) nitrate or plutonium(IV) chloride with potassium iodate and dilute nitric acid.[4] It can crystallize in the tetragonal crystal system with space group P42/n.[2]
