Abstract
A solid state melting and annealing route was used to prepare Cu6Te3S, a copper telluride sulfide representing a filled variant of the Cr3Si structure type. The title compound exhibits a reversible phase transition at 404 K which was confirmed by thermal analysis, temperature dependent X-ray single crystal and powder diffractometry. Both polymorphs crystalize cubic in space groups
