Synthesis

Plutonium oxyiodide is produced in a reaction of plutonium dioxide with hydrogen iodide:^[4]

PuO₂ + ½H₂ + HI → PuOI + H₂O

It can also be made by passing hydrogen iodide through heated plutonium(IV) oxide:^[5]

2PuO₂ + 4HI → 2PuOI + 2H₂O + I₂

Physical properties

Plutonium oxyiodide forms bright green crystals of the tetragonal crystal system, space group P4/nmm.^[6]
