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.
Thorium tetrabromide (ThBr 4, white, m.p. 679 °C) can be produced either by reacting thorium(IV) hydroxide with hydrobromic acid (which has the disadvantage of often resulting in products contaminated with oxybromides) or by directly reacting bromine or hydrogen bromide with thorium metal or compounds. [14]
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]
