Gadolinium(III) iodide is an iodide of gadolinium, with the chemical formula of GdI3.
Preparation
Gadolinium(III) iodide can be obtained by the reaction between gadolinium(III) oxide and hydroiodic acid, crystallizing into the hydrate form. The hydrate form can be heated with ammonium iodide to form the anhydrous form.[1]
- Gd2O3 + 6 HI → 2 GdI3 + 3 H2O
Reactions
Gadolinium(III) iodide reacts with gadolinium and zinc in an argon atmosphere heated to 850 °C to obtain Gd7I12Zn.[2] It reacts with gadolinium, carbon, and gadolinium nitride in a tantalum tube at 897 °C to obtain nitrocarbide Gd4I6CN.[3]
