Cyanide-bridged oligonuclear complex features and attractions

The synthetic and structural chemistry as well as some physical and chemical properties of cyanide-bridged complexes containing two or more metal building blocks are discussed. Emphasis is laid on molecular shape and design and their consequences, including the effects of cyanide-isocyanide isomerism. Redox phenomena and molecular magnetism have been dealt with in relation to electronic communication across the cyanide bridges and metal-metal charge transfer. Long-range interactions between remote metal centers are discussed, and the few cases where they lead to remote chemical reactions are listed.
