Tellurium tetrabromide (Te Br 4) is an inorganic chemical compound. It has a similar tetrameric structure to TeCl 4. [3] It can be made by reacting bromine and tellurium. [4] In the vapour TeBr 4 dissociates: [3] TeBr 4 → TeBr 2 + Br 2. It is a conductor when molten, dissociating into the ions TeBr 3 + and Br −.
Structure of tellurium tetrachloride, tetrabromide and tetraiodide. The +2 oxidation state is exhibited by the dihalides, TeCl 2, TeBr 2 and TeI 2.The dihalides have not been obtained in pure form, [3]: 274 although they are known decomposition products of the tetrahalides in organic solvents, and the derived tetrahalotellurates are well-characterized:

Ditellurium bromide is the inorganic compound with the formula Te 2 Br. It is one of the few stable lower bromides of tellurium. It is one of the few stable lower bromides of tellurium. Unlike sulfur and selenium , tellurium forms families of polymeric subhalides where the halide/chalcogen ratio is less than 2.

The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1]In principle, Te 2− is formed by the two-e − reduction of tellurium.
Tellurium tetrachloride is the gateway compound for high valent organotellurium compounds. Arylation gives, depending on conditions, Te(C 6 H 4 R) 2 Cl 2, [Te(C 6 H 4 R) 5] −, [Te(C 6 H 4 R) 6] 2−. [6] TeCl 4 has few applications in organic synthesis. Its equivalent weight is high, and the toxicity of organotellurium compounds is problematic.
