Tellurium tetrabromide (TeBr<sub>4</sub>) is an inorganic chemical compound. It has a similar tetrameric structure to TeCl<sub>4</sub>. It can be made by reacting bromine and tellurium. In the vapour TeBr<sub>4</sub> dissociates:
It is a conductor when molten, dissociating into the ions TeBr<sub>3</sub><sup>+</sup> and Br<sup>−</sup>. When dissolved in benzene and toluene, TeBr<sub>4</sub> is present as the unionized tetramer Te<sub>4</sub>Br<sub>16</sub>. In solvents with donor properties such as acetonitrile, CH<sub>3</sub>CN ionic complexes are formed which make the solution conducting:
