· Na4 As2 Au2

Na₄As₂Au₂ is an intermetallic compound containing sodium, arsenic, and gold elements, representing a rare ternary metal system. This is a research-phase material rather than a commercial engineering alloy; compounds in this compositional space are primarily of academic interest for studying unusual crystal structures, electronic properties, and metallic bonding behavior in high-complexity systems. Such sodium-gold intermetallics are not typically deployed in mainstream engineering applications but may be investigated for potential niche applications in thermoelectrics, specialized alloys, or fundamental materials science exploring phase diagrams and electronic behavior.
