Preparation and properties
Te2Br is a gray solid. Its structure consists of a chain of Te atoms with Br occupying a doubly bridged site. It is prepared by heating tellurium with the appropriate stoichiometry of bromine near 215 °C. The corresponding chloride and iodide, Te2Cl and Te2I, are also known. Other tellurium bromides include the yellow liquid Te2Br2, the orange solid TeBr4,Zhengtao Xu "Recent Developments in Binary Halogen–Chalcogen Compounds, Polyanions and Polycations" in Handbook of Chalcogen Chemistry: New Perspectives in Sulfur, Selenium and Tellurium, Francesco Devillanova, Editor, 2006, RSC. pp. 381-416. Royal Society and the greenish-black solid TeBr2. Complexes of the type TeBr2(thiourea)2 are well characterized.References
