Pr4CuS7
metal· JVASP-141723· Pr4CuS7
Pr₄CuS₇ is a rare-earth copper sulfide compound belonging to the family of ternary chalcogenides, combining praseodymium with copper and sulfur. This material is primarily of research and exploratory interest rather than established industrial production; compounds in this family are investigated for potential applications in thermoelectric devices, photocatalysis, and solid-state electronics where the layered sulfide structure and rare-earth electronic properties may offer functional advantages over conventional semiconductors or intermetallic compounds.
