CuSe2Cl is a mixed-valent copper selenide chloride compound combining copper, selenium, and chlorine in a single-phase structure. This material belongs to the family of layered metal chalcohalides and remains largely experimental; it is not widely established in commercial applications. Research interest in such compounds typically centers on their potential as semiconductors, ionic conductors, or photovoltaic absorbers, where the combination of heavy elements and layered crystal structure can yield unusual electronic or photocatalytic properties.
