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:[3]

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.[4]

## Reactions

Ytterbium(III) iodide decomposes to ytterbium(II) iodide upon heating:[5]

2 YbI3 → 2 YbI2 \+ I2
