Terbium(III) iodide (TbI3) is an inorganic chemical compound.

## Production

Terbium(III) iodide can be produced by reacting terbium and iodine.[2]

2 Tb + 3 I
2 → 2 TbI

An alternative method is reacting terbium and mercury(II) iodide at 500 °C.[3]

## Structure

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]
