Transition metal peroxides
Binary transition metal peroxides, compounds containing only metal cations and peroxide anions, are rare. Metal dioxides, on the other hand, are pervasive, such as MnO2 and rutile (TiO2). Well characterized examples of transition metal peroxides include the d metal cations: zinc peroxide (ZnO2), two polymorphs (both explosive) of mercury peroxide (HgO2), and cadmium peroxide (CdO2).
