Plutonium(III) iodide

Plutonium iodide is the iodide of plutonium with the chemical formula PuI₃.

Preparation

Plutonium iodide can be formed by the reaction of plutonium and mercury iodide:
It can also be produced by reacting plutonium and hydrogen iodide at 450 °C. Even if there is only a small amount of oxygen and water in the reaction, the generated plutonium iodide will immediately hydrolyze into plutonium oxyiodide.

Plutonium iodide is a green solid with a melting point of 777 °C. It is orthorhombic, space group Ccmm, lattice parameters a = 433 pm, b = 1395 pm and c = 996 pm.
