Tellurium tetrabromide
open-in-new
<p>Tellurium tetrabromide (<a href="/facts/Tellurium/v7QvfIvS">Te</a><a href="/facts/Bromine/oLfj3C7D">Br4</a>) is an <a href="/facts/Inorganic/TfFfzxSz">inorganic</a> <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a>. It has a similar tetrameric structure to <a href="/facts/Tellurium_tetrachloride/UxAbGDjb">TeCl4</a>. It can be made by reacting bromine and tellurium. In the vapour TeBr4 dissociates: </p> TeBr4 → TeBr2 + Br2 <p>It is a conductor when molten, dissociating into the ions TeBr3+ and Br−. When dissolved in <a href="/facts/Benzene/Fguue7nr">benzene</a> and <a href="/facts/Toluene/Pzdt8dwD">toluene</a>, TeBr4 is present as the unionized tetramer Te4Br16. In solvents with donor properties such as <a href="/facts/Acetonitrile/fNpbvRp6">acetonitrile</a>, CH3CN ionic complexes are formed which make the solution conducting: </p> TeBr4 + 2CH3CN → (CH3CN)2TeBr3+ + Br−
