Tritellurium dichloride explained

Tritellurium dichloride is the inorganic compound with the formula Te3Cl2. It is one of the more stable lower chlorides of tellurium.

Preparation and properties

Te3Cl2 is a gray solid. Its structure consists of a long chain of Te atoms, with every third Te center carrying two chloride ligands for the repeat unit -Te-Te-TeCl2-. It is a semiconductor with a band gap of 1.52 eV, which is larger than that for elemental Te (0.34 eV).[1] It is prepared by heating Te with the appropriate stoichiometry of chlorine.[2]
