Hydrogen Peroxide - an overview ScienceDirect Topics

Unlike the alkali metal and alkaline earth metal peroxides, binary transition metal peroxides, that is, compounds containing only metal cations and peroxide anions, are rare. Metal dioxides are pervasive, such as MnO2 and rutile (TiO2), but these are oxides, not peroxides. Well characterized examples include the d metal cations: zinc peroxide (ZnO2), two polymorphs (both explosive) of mercury peroxide (HgO2), and cadmium peroxide (CdO2).
