摘要: Mixed-valence systems may exhibit the property of electron localization, which distinguishes them sharply from molecules, complex ions or solid state compounds usually encountered in chemistry. Where localization or, as it is often termed, valence trapping, occurs, possible to distinguish between subsystems differ each other by presence one more electrons. Thus, state, Pb(II) and Pb(IV) can be simultaneously identified type Rh(NH3)6PbC16, Fe(II) Fe(III) many naturally-occurring silicate minerals.
