Tellurium tetrabromide (TeBr4) is an inorganic chemical compound. It has a similar tetrameric structure to TeCl4.[1] It can be made by reacting bromine and tellurium. In the vapour TeBr4 dissociates:[1]
TeBr4 → TeBr2 + Br2It is a conductor when molten, dissociating into the ions TeBr3+ and Br-. When dissolved in benzene and toluene, TeBr4 is present as the unionized tetramer Te4Br16.[1] In solvents with donor properties such as acetonitrile, CH3CN ionic complexes are formed which make the solution conducting:
TeBr4 + 2CH3CN → (CH3CN)2TeBr3+ + Br-
