Titanium(II) iodide is the inorganic compound with the formula TiI2. It is a black micaceous solid. It adopts the cadmium iodide structure, featuring octahedral Ti(II) centers. It arises via the reaction of the elements:[1]
Ti + I2 → TiI2
As such, it is an implied intermediate in the van Arkel–de Boer process for the purification of titanium metal.
