Terbium(III) iodide (TbI3) is an inorganic chemical compound.
Preparation Terbium(III) iodide can be produced by reacting terbium and iodine.WebElements: Chemical reactions of the element Terbium
Terbium iodide hydrate can be crystallized from solution by reacting hydriodic acid with terbium, terbium(III) oxide, terbium hydroxide or terbium carbonate:
An alternative method is reacting terbium and mercury(II) iodide at 500 °C.
Structure Terbium(III) iodide adopts the bismuth(III) iodide (BiI3) crystal structure type, with octahedral coordination of each Tb3+ ion by 6 iodide ions.
