Tellurium tetrabromide ( Te Br₄) is an

inorganic In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...

chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element ...

. It has a similar tetrameric structure to TeCl₄.''Inorganic Chemistry'',Egon Wiberg, Arnold Frederick Holleman Elsevier 2001 It can be made by reacting bromine and tellurium. In the vapour TeBr₄ dissociates: :TeBr₄ → TeBr₂ + Br₂ It is a conductor when molten, dissociating into the ions TeBr₃⁺ and Br⁻. When dissolved in

benzene Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, ...
