· Li4 S4 Au4

Li₄S₄Au₄ is an experimental quaternary compound combining lithium, sulfur, and gold in a fixed stoichiometric ratio, classified as a semiconductor. This material belongs to the family of mixed-metal chalcogenides and represents early-stage research into multifunctional inorganic compounds that may bridge ionic, electronic, and catalytic properties. While not yet commercialized, compounds in this chemical space are being investigated for energy storage, solid-state battery components, and catalytic applications where the combination of lithium-sulfur chemistry with gold's chemical stability and electron affinity could offer novel synergies.
