Ditellurium bromide is the inorganic compound with the formula Te<sub>2</sub>Br. 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.
Te<sub>2</sub>Br 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 ðC, or reduction at room temperature of tellurium tetrabromide with tellurium metal in a tetrachloroaluminate ionic liquid. The corresponding chloride and iodide, Te<sub>2</sub>Cl and Te<sub>2</sub>I, are also known.
Other tellurium bromides include the yellow liquid Te<sub>2</sub>Br<sub>2</sub>, the orange solid TeBr<sub>4</sub>, and the greenish-black solid TeBr<sub>2</sub>. Complexes of the type TeBr<sub>2</sub>(thiourea)<sub>2</sub> are well characterized.
