Ditellurium bromide is the inorganic compound with the formula Te2Br. It is one of the few stable lower bromides of tellurium. Unlike sulfur and selenium, tellurium forms families of polymeric subhalides where the chalcogen/halide ratio is less than 2.[1]
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 Te with the appropriate stoichiometry of bromine near 215 °C. The corresponding chloride and iodide, Te2Cl and Te2I, are also known.[2]
The only other tellurium bromides are the yellow liquid Te2Br2 and the orange solid TeBr4.[3]
