Synergy Between Dynamics and Reactivity at Clusters and Surfaces

The analogy between the chemistry of molecular transition metal clusters and the processes of chemisorption and catalysis at metal surfaces (the Cluster Surface analogy) has for a number of years provided an interplay between experimental and theoretical inorganic and physical chemists. This collaborative approach has borne fruit in the use of well-defined modes of metal-ligand bonding in discrete molecular clusters, models for metal-ligand binding on surfaces. Some of the key topics discussed in this book are: mechanisms of the fluxional behaviour in clusters in the liquid phase and the connections with diffusion processes on extended surfaces, and the role of metal-metal bond breaking in diffusion; analogies in the structure of chemisorbed species and related ligands on metallic clusters; analogies between benzene surface chemistry on extended metal surfaces and on metal surfaces in molecular cluster compounds with particular reference to structural distortions; and the role of mobile precursors for dissociation of chemisorption on extended metals and on clusters.
