Ytterbium(III) iodide is one of ytterbium's iodides, with the chemical formula of YbI3.

Preparation

Ytterbium(III) iodide can be prepared by reacting metallic ytterbium with iodine at 500°C with a 30 atm pressure:Asprey, L. B.; Keenan, T. K.; Kruse, F. H. Preparation and crystal data for lanthanide and actinide triiodides. Inorg. Chem., 1964. 3 (8): 1137-1240

: 2 Yb + 3 I2 → 2 YbI3

Ytterbium(III) oxide, ytterbium(III) hydroxide or ytterbium(III) carbonate can react with hydroiodic acid to obtain ytterbium(III) iodide in aqueous solution:

: Yb2O3 + 6 HI → 2 YbI3 + 3 H2O

: Yb(OH)3 + 3 HI → YbI3 + 3 H2O

: Yb2(CO3)3 + 6 HI → 2 YbI3 + 3 H2O + 3 CO2

The ytterbium(III) iodide hydrate crystallized from the solution can be heated with ammonium iodide to obtain the anhydrous form.无机化学丛书 第七卷 钪 稀土元素. 科学出版社. pp 211

Reactions

Ytterbium(III) iodide decomposes to ytterbium(II) iodide upon heating:{{cite journal|journal=Zeitschrift für anorganische und allgemeine Chemie|volume=201|issue=1|language=en|date=1931-11-10|pages=207–220|doi=10.1002/zaac.19312010119|url=https://onlinelibrary.wiley.com/doi/10.1002/zaac.19312010119|title=Zur Kenntnis der Halogenide der seltenen Erden.
