Alkaline earth metals ozonides

In addition to the oxides MO, peroxides MO2 are known for the heavier alkaline earth metals and there is some evidence for yellow superoxides M(02)2 of Ca, Sr and Ba impure ozonides Ca(03)2 and Ba(03)2 have also been reported. As with the alkali metals, stability...

The deposition of alkaline-earth-metal atoms and ozone molecules at high dilution in argon at 15 K yields species showing intense bands in the i.r. at 800 and 450—650 cm-1. Those at 800 cm"1 showed the appropriate isotopic shifts for assignment of v3 for the ozonide ion, Oj. The use of scrambled isotopic ozones indicates that the metal cation is symmetrically bound to the ozonide ion, which contains three O atoms, with two of these equivalent. In addition, calcium and barium mixtures with ozone contain several metal oxide species tentatively identified as (CaO)2, Ca02,BaO, and (BaO)2, respectively.73...

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.
