O6 Na1 Ba2 Os1

This is a barium sodium osmium oxide compound (Ba₂NaOsO₆), a mixed-metal oxide semiconductor belonging to the perovskite or perovskite-related family. This is a research-phase material studied primarily in materials science for its potential electronic and magnetic properties. The compound's notable feature is the combination of osmium—a rare, high-density metal—with alkaline earth and alkali elements, making it of interest in solid-state chemistry for understanding structure-property relationships in complex oxides, though it remains largely experimental without established commercial applications.
