Tellurium tetrabromide (TeBr4) is aninorganicchemical compound. It has a similar tetrameric structure toTeCl4.[3] It can be made by reacting bromine and tellurium.[4] In the vapour TeBr4 dissociates:[3]
It is a conductor when molten, dissociating into the ions TeBr3+ and Br−. When dissolved inbenzene andtoluene, TeBr4 is present as the unionized tetramer Te4Br16.[3] In solvents with donor properties such asacetonitrile, CH3CN ionic complexes are formed which make the solution conducting:
