Infobox references

Tellurium tetrabromide (TeBr4) is an inorganic chemical compound. It has a similar tetrameric structure to TeCl4.[3] It can be made by reacting bromine and tellurium.[4] In the vapour TeBr4 dissociates:[3]

TeBr4 → TeBr2 \+ Br2

It 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.[3] In solvents with donor properties such as acetonitrile, CH3CN ionic complexes are formed which make the solution conducting:

TeBr4 \+ 2CH3CN → (CH3CN)2TeBr3+ \+ Br−
