Thulium(III) iodide is an iodide of thulium, with the chemical formula of TmI₃. Thulium(III) iodide is used as a component of metal halide lamps.^[3]

Preparation

Mercury(II) iodide can be heated with thulium to obtain thulium(III) iodide:^[4]

2 Tm + 3 HgI₂ → 2 TmI₃ + 3 Hg

The mercury produced in the reaction can be removed by distillation.^[5]^[4]

The thulium(III) iodide hydrate crystallized from solution can be heated with ammonium iodide to obtain the anhydrous form.^[6]^[4]

Properties

Thulium(III) iodide is a yellow, highly hygroscopic solid with a bismuth(III) iodide-type crystal structure.^[4] It forms in the hexagonal crystal system.^[6] Its hydrate can be heated in air to obtain TmOI. Its anhydrous form can be heated with thulium to obtain TmI₂:^[7]

2 TmI₃ + Tm → 3 TmI₂
