Tellurium tetraiodide (TeI4) is an inorganic chemical compound. It has a tetrameric structure which is different from the tetrameric solid forms of TeCl4 and TeBr4. In TeI4 the Te atoms are octahedrally coordinated and edges of the octahedra are shared.TeI4 can be prepared from the elements or by reacting Te and iodomethane CH3I. In the vapour TeI4 dissociates:TeI4 → TeI2 + I2It is a conductor when molten dissociating into the ions TeI3+ and I−.
