Dynamic and Physical Properties - An Overview

An important frontier in cluster chemistry is the effect of electron count on reactivity. Are clusters merely passive electron reservoirs or does the number of electrons have a critical influence on reactions other than electron transfer Conversely, how does the number of metal atoms, the relative ratio of heterometals, and the specific ligand set relate to the ability of clusters to enter into redox reactions These questions are of fundamental interest, but the answers also may have practical consequences, for example, in the development of metal nanoparticles or colloids to act as electrocatalysts. In a final group of articles Longoni and coworkers review the ability of homoleptic carbonyl clusters to act as electron-sinks , Zanello and Fab-rizi de Biani examine the effect of heterometallic interactions on cluster redox aptitude, and Ignaczak and Gomes report on modelling of electrode interactions with metal clusters.
