Chemical compound
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.
