Ytterbium(III) iodide is one of ytterbium's iodides, with the chemical formula of YbI3.
Ytterbium(III) iodide can be prepared by reacting metallic ytterbium with iodine at 500°C with a 30 atm pressure: [3]
Ytterbium(III) oxide, ytterbium(III) hydroxide or ytterbium(III) carbonate can react with hydroiodic acid to obtain ytterbium(III) iodide in aqueous solution:
The ytterbium(III) iodide hydrate crystallized from the solution can be heated with ammonium iodide to obtain the anhydrous form. [4]
Ytterbium(III) iodide decomposes to ytterbium(II) iodide upon heating: [5]
