Titanium(III) iodide is an inorganic compound with the formula TiI3. It is a dark violet solid that is insoluble in solvents, except upon decomposition.

Preparation and structure

Titanium(III) iodide can be prepared by reaction of titanium with iodine:[2]

It can also be obtained by reduction of TiI4, e.g., with aluminium .[3]

In terms of its structure, the compound exists as a polymer of face-sharing octahedra. Above 323 K, the Ti---Ti spacing are equal, but below that temperature, the material undergoes a phase transition. In the low temperature phase, the Ti---Ti contacts are alternating short and long. The low temperature structure is similar to that of molybdenum tribromide.[1]
