· JVASP-19609· NaAu2

NaAu2 is an intermetallic compound composed of sodium and gold, belonging to the class of gold-based intermetallic metals. This material is primarily of research and academic interest rather than established in mainstream industrial production, studied for its unique crystal structure and potential applications in advanced alloys and materials science. The compound is notable within the broader context of gold intermetallics for investigating phase stability, electronic properties, and potential catalytic or functional applications where gold's chemical properties combine with sodium's reducing character.
