Cationic clusters electron

There are only a few examples of cationic clusters, which is in keeping with the postulated electron-sink effect of the system of metal-metal bonds. This hypothesis is supported by examination of some properties of the clusters Co3(CO)9(/i3-CR) as reported previously207 209. ...

The formation of hydrated electrons (in the water-saturated zeolites X and Y) has been identified through their absorption spectra, their short lifetimes distinct from the long-lived cation cluster-trapped electrons, and their reactivity towards typical hydrated electron quenchers such as methylviologen. Based on these spectra (Fig. 5), yields between 4 x 10 mol and 6 x 10 mol were measured for electrons in fully hydrated NaY. These high radiolytic yields were also explained by electron transfer from the ionized zeolitic skeleton to the water clusters [Eqs. (1) and (7)].
