Ba4 Au4

Ba₄Au₄ is an intermetallic compound combining barium and gold in a 1:1 stoichiometric ratio, belonging to the class of binary metallic intermetallics. This is a research-phase material with limited industrial deployment; it is primarily studied for its potential electronic and structural properties arising from the combination of an alkaline-earth metal (barium) with a noble metal (gold), making it of interest in materials physics and theoretical solid-state chemistry. The compound represents exploration within intermetallic phase diagrams where such combinations may exhibit novel semiconducting or catalytic behavior not found in the constituent elements alone.
