Abstract
Chemical reactions and pathways involving a metal cluster change dramatically with the cluster size and composition. These dependences originate essentially from the electron correlation of the cluster, and hence are closely related to the geometrical and electronic structures of the cluster. Along with our recent studies, the following subjects are reviewed: (i) reactivity, (ii) geometrical and electronic structures in relation to the reactivity, (iii) reaction dynamics, and (iv) catalytic properties.
