Saline peroxides contain $O22−$-anions. The most important are the peroxides of the alkali and alkaline earth metals. (Examples: $Na2O2$, $BaO2$). These compounds tend to explode by contact with organic materials. With water they decompose generating hydrogen peroxide $HOOH$.

In peroxo complexes, $O22−$ acts as a ligand. These are dioxometal cyclic compounds, i.e. three-membered rings containing two oxygen and one metal atom as well as multicycle complexes bridged by -$O-O$-.

Covalently bound peroxides have the general formula $X-O-O-Y$ and easily decompose into . Aqueous solutions of hydrogen peroxide are being used as bleaching or . $ClOOCl$ is a key factor in ozone depletion of stratospheric ice clouds (ozone hole process). Organic peroxides, such as di-tert-butylperoxide $(CH3)3C-O-O-C(CH3)3$ and dibenzoylperoxide $C6H5-CO-O-O-CO-C6H5$ are used as initiators in . Peroxides are unwanted by-poducts during the of organic compounds.
