· JVASP-29653· CuP4Se4I

CuP₄Se₄I is a mixed-anion copper chalcogenide compound combining copper, phosphorus, selenium, and iodine into a single crystalline phase. This is a research-stage material rather than an established industrial product, belonging to the family of multinary semiconductors and ion-conducting compounds that have attracted attention for their tunable electronic and ionic properties. The material's potential relevance lies in solid-state energy storage, photovoltaic applications, or ion-transport-based devices where the mixed-anion structure could enable novel charge-carrier dynamics or superionic behavior.
