Ditellurium bromide is theinorganic compound with the formulaTe2Br. It is one of the few stable lower bromides of tellurium. Unlikesulfur andselenium, tellurium forms families of polymericsubhalides where the halide/chalcogen ratio is less than 2.[2]
Te2Br is a gray solid. Its structure consists of a chain of Te atoms with Br occupying a doublybridged site. It is prepared by heating tellurium with the appropriate stoichiometry of bromine near 215 °C,[3] or reduction at room temperature oftellurium tetrabromide with tellurium metal in atetrachloroaluminate ionic liquid.[4] The corresponding chloride and iodide,Te2Cl andTe2I, are also known.[3]
Other tellurium bromides include the yellow liquid Te2Br2, the orange solidTeBr4,[5] and the greenish-black solid TeBr2.[6] Complexes of the type TeBr2(thiourea)2 are well characterized.[7]
