Ditellurium bromide is the inorganic compound

Inorganic compound

Inorganic compounds have traditionally been considered to be of inanimate, non-biological origin. In contrast, organic compounds have an explicit biological origin. However, over the past century, the classification of inorganic vs organic compounds has become less important to scientists,...

Bromide

A bromide is a chemical compound containing bromide ion, that is bromine atom with effective charge of −1. The class name can include ionic compounds such as caesium bromide or covalent compounds such as sulfur dibromide.-Natural occurrence:...

. It is one of the few stable lower bromides of tellurium. Unlike sulfur and selenium, tellurium forms families of polymeric subhalide

Subhalide

In chemistry, subhalide usually refers to inorganic compounds where the halide/metal ratio requires metal-metal bonding, sometimes extensively. Many compounds meet this definition.-Examples:...

s where the chalcogen/halide ratio is less than 2.

Preparation and properties

Te₂Br is a gray solid. Its structure consists of a chain of Te atoms with Br occupying a doubly bridged site

Bridging ligand

A bridging ligand is a ligand that connects two or more atoms, usually metal ions. The ligand may be atomic or polyatomic. Virtually all complex organic compounds can serve as bridging ligands, so the term is usually restricted to small ligands such as pseudohalides or to ligands that are...

. 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.

The only other tellurium bromides are the yellow liquid Te₂Br₂ and the orange solid TeBr₄

Tellurium tetrabromide

Tellurium tetrabromide is an inorganic chemical compound. It has a similar tetrameric structure to TeCl4. It can be made by reacting bromine and tellurium.. In the vapour TeBr4 dissociates :It is a conductor when molten, dissociating into the ions TeBr3+ and Br−Solutions in benzene and...
