This book provides a basic introduction to metal-metal bonded carbonyl dimers and clusters and covers their structures and syntheses. It discusses localized bonding schemes and their limitations, and provides an introduction to bonding schemes appropriate for clusters. It also offers an introduction to derivatives, including hydrides, phosphine derivatives, dimers and clusters with organic ligands, and clusters containing units with p-block elements, including interstitial atoms. The final section of the book provides problems which can be used to test readers' knowledge of the principles as well as their ability to interpret experimental data. Concise and extensively illustrated, Metal-Metal Bonded Carbonyl Dimers provides an accessible overview, and can be used as a companion volume to Cluster Molecules of the p-block Elements.
