Terbium(III) iodide (TbI3) is an inorganic chemical compound.
Terbium(III) iodide can be produced by reacting terbium and iodine.[2]
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.[3]
Terbium(III) iodide adopts the bismuth(III) iodide (BiI3) crystal structure type,[4][3] with octahedral coordination of each Tb3+ ion by 6 iodide ions.[5]
