Tellurium is an inorganic chemical compound of tellurium from the group of chlorides.

Production and representation

Tellurium can be obtained by reacting tellurium with chlorine.

Properties

Tellurium is a moisture- sensitive white to yellow solid with a pungent odor, which decomposes in water with the formation of tellurium dioxide and hydrogen chloride. It dissolves in moist air with partial hydrolytic decomposition and is soluble in ethanol and toluene. Its melt is colored yellow, the orange vapor. From about 500 ° C, the compound decomposes to chlorine delivery, the decomposition at 1000 ° C is complete. In the gaseous state, the monomer and corresponds to the structure of sulfur tetrafluoride. In the solid state, it has a structure of the Kuban type which can be described as being composed of four linked via halide bridges TeCl3 Cl units.

Use

Tellurium can be used for synthesis of organic chemistry.
