Samarium(III) oxyiodide

Samarium(III) oxyiodide is an inorganic compound with the chemical formula SmOI. It can be obtained by reacting samarium(II) iodide with dry oxygen.^[2] It is oxidized when heated to 335 °C in air, and starts to generate nSmOI·Sm₂O₃ (n is 7, 4, 2 respectively) at 460 °C, 560 °C, and 640 °C, and completely transforms at 885 °C for samarium oxide.^[3] It can catalyze the rearrangement of propylene oxide derivatives to methyl ketones.^[2] It reacts with samarium(III) iodide, sodium iodide, and sodium at 903 K in a tantalum container to obtain black Sm₄OI₆.^[4]
