PmMgAu2 is an intermetallic compound combining promethium, magnesium, and gold in a 1:1:2 stoichiometry. This is an experimental material studied primarily in research contexts rather than established industrial production; intermetallics of this composition are of academic interest for understanding phase stability and potential applications where the unique combination of a radioactive rare earth element (promethium), a lightweight alkaline earth metal (magnesium), and a noble metal (gold) might offer unusual property combinations. Such compounds are unlikely to see widespread engineering adoption due to promethium's extreme scarcity, radioactivity, and cost, though the material family may inform design of more practical ternary or quaternary alloys for high-performance or specialized applications.
