It can be created by reacting rubidium superoxide (RbO₂) with ozone (O₃) in a liquid ammonia solution.^[3]

RbO₂ + O₃ → RbO₃ + O₂

The chemical forms in two crystal structures, the low temperature α-RbO₃ (P2₁),^[1] and β-RbO₃ (P2₁/c)^[4] Detailed structural analysis finds the ozonide anions are significantly off-center from the surrounding rubidium atoms.^[5]

Since ozonide anion is magnetic, electron paramagnetic resonance measurements of rubidium ozonide have determined the g-values of the ozonide anion.^[2]
