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