Redox properties of polymetallic

More recently, it has become clear that many polynuclear compounds undergo electron-transfer reactions, and several reviews devoted wholly or partly to this subject have appeared 1-4). Studies of the redox properties of polymetallic species can provide information on the nature of the highest occupied molecular orbital (HOMO) or lowest unoccupied molecular orbital (LUMO), on the possible cooperativity between metal sites, on the existence of mixed-valence compounds, and on the ways in which one-electron (or, more rarely, two-electron) changes affect structure and reactivity. 

My intention is to develop, as systematically as possible, the redox properties of polymetallic systems in solution. An understanding of redox properties and of metal-metal interactions is essential in order to exploit polymetallic systems. Most of the examples are based on the findings of my own research group with three different classes of compounds which differ in the nature and/or the extent of the metal-metal interaction.
