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:
In many tellurium bromide compounds, tellurium atoms link up in a helix, similar to pure tellurium structure. In Rhenium compounds tellurium atoms form a cluster with rhenium atoms. In some materials, tellurium forms a honeycomb like structure containing tubes filled with bromine and the other elements.

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.
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.
Lead forms one hydride, which has the formula PbH 4. Lead forms dihalides and tetrahalides with fluorine and chlorine, and forms a dibromide and a diiodide, although the tetrabromide and tetraiodide of lead are unstable. Lead forms four oxides, a sulfide, a selenide, and a telluride. [9]
Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
