The first oxidation is a chemically and electrochemically reversible process whereas the second varies from nearly reversible to irreversible at room temperature. We have generated and investigated the mixed-valence monocations and observed CO band shifts of ca 25 cm-1 and the appearance of new bands in the visible regime at ca 720 to 800 and 430 to 450 nm." .
