Metal clusters occupy a central role in chemistry. Aspects of cluster chemistry impinge on branches of the subject ranging from organometallic chemistry, through coordination chemistry, homogeneous and heterogeneous catalysis to solid-state chemistry and catalysis. Research in metal clusters is an interdisciplinary enterprise that has exploded rapidly in importance over the past twenty years because metal clusters exhibit increasingly interesting bonding as well as electronic, structural and physical, and chemical and catalytic properties. Several reviews and books have appeared in the past emphasising the key role that metal clusters play in chemistry, materials science, nanotechnology and catalysis, but no up to date single source dealing with the recent developments in metal cluster chemistry is currently available. The purpose of this book is to provide a general source of references for workers including experimental and theoretical chemists and physicists in this interdisciplinary field, and covering both fundamental and applied science
