Rubidium ozonide is an oxygen rich compound of rubidium with the chemical formula RbO3. It consists of rubidium cations Rb+ and ozonide anions O−3. It can be created by reacting rubidium superoxide (RbO2) with ozone (O3) in a liquid ammonia solution.
RbO2 + O3 → RbO3 + O2 The chemical forms in two crystal structures, the low temperature α-RbO3 (P21), and β-RbO3 (P21/c) Detailed structural analysis finds the ozonide anions are significantly off-center from the surrounding rubidium atoms. Since ozonide anion is magnetic, electron paramagnetic resonance measurements of rubidium ozonide have determined the g-values of the ozonide anion.
