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-.[2] It is a semiconductor with a band gap of 1.52 eV, which is larger than that for elemental Te (0.34 eV).[3] It is prepared by heating Te with the appropriate stoichiometry of chlorine.[4]
