Metal ozonides

The stability of the alkali metal ozonides increases from Li to Cs alkaline-earth ozonides exhibit a similar stability pattern. Reaction of metal ozonides with water proceeds through the intermediate formation of hydroxyl radicals. 

Petrocelli, A. W. et al., J. Chem. Educ., 1962, 39, 557 This is the least stable of the alkali-metal ozonides. 

Complexes of alkali metal ozonides with cryptand[2.2.2] and various crown ethers have been prepared in order to increase the solubility range of these compounds in solvents other than NH3. The first structural analysis reported for such complexes was that of ([18-crown-6]Rb)03 NH3 (334), carried out by single-crystal XRD. The Rb+ cation is part of...

The deep red ozonide ion has a bent structure, and sodium ozonide is isostructural with sodium nitrite (NaNC>2). The X-ray structural data of the alkali metal ozonides show that an increase in cationic size corresponds to a decrease in 0-0 bond length and an increase in 0-0-0 angle, as summarized in the following table ...

The ozonide subsequently reacts with water to give KOH(aq) and 02(g). By using other methods of preparation, it has been possible to prepare other alkali metal ozonides. However, the stability of these ozonides decreases as the size of the metal cation decreases because, as discussed in Chapter 21, a large polarizable anion, such as Os , is not particularly stable in the presence of small, highly polarizing cations.
