Notes:
Concentrated solutions of the ozonides LiO3 and NaO3 in anhydrous liquid ammonia were obtained for the first time by using an ion exchange reaction that starts from CsO3. No solid LiO3 or NaO3 can be precipitated. Upon removal of the solvent, the ozonide anion oxidises ammonia, resulting in the precipitation of LiOH and NaOH, respectively. This behaviour is in sharp contrast to that of solutions of KO3, RbO3 and CsO3. Proof of the existence of LiO3 and NaO3 in the solutions is provided by complexation of the cations with cryptands, which leads to solid (Li[2.1.1])O3 and (Na[2.2.2])O3. Crystal structure analysis shows that these are ionic solids containing the V-shaped O3- anion.
