RbCuON2

RbCuON₂ is an experimental mixed-metal oxide-nitride ceramic compound containing rubidium, copper, oxygen, and nitrogen elements. This material represents research into ternary and quaternary ceramic systems that combine oxidic and nitridic bonding, a class of compounds explored for potential electronic, optical, or catalytic applications where unconventional coordination chemistry might offer advantages over traditional single-anion ceramics. Such materials remain largely in the research phase and are not established in mainstream industrial production.
