N6 O12 Na3 Rh1

This is a sodium rhodium oxide compound (Na₃RhO₆), a mixed-metal oxide semiconductor belonging to the perovskite or layered oxide family. While not a common commercial material, compounds in this class are primarily explored in electrochemistry and photocatalysis research, where transition metal oxides like rhodium oxides offer high catalytic activity and tunable electronic properties. The sodium content and rhodium's known catalytic properties suggest potential applications in energy conversion and chemical processing, though this specific composition remains largely experimental.
