Rb3Au7

Rb3Au7 is an intermetallic compound composed of rubidium and gold, belonging to the class of alkali metal–precious metal intermetallics. This material is primarily of research and academic interest rather than established in commercial production, as such compounds are generally too brittle and chemically reactive for conventional engineering applications. The material family is notable in solid-state chemistry and materials science for understanding phase diagrams, crystal structures, and electronic properties of alkali-noble metal systems, with potential relevance to specialized fields such as catalysis research, electrochemistry, or advanced alloy development.
