Organometallic chemistry is the study of chemical compounds containing bonds between carbon and a metal. Since many compounds without such bonds are chemically similar, an alternative may be compounds containing metal-element bonds of a largely covalent character. Examples of such organometallic compounds include all Gilman Reagents, which contain lithium and copper. Tetracarbonyl nickel, and ferrocene are examples of organometallic compounds containing transition metals. In addition to the traditional metals, lanthanides, actinides, and semimetals, elements such as boron, silicon, arsenic, and selenium are considered to form organometallic compounds. Organometallic compounds are a diverse and versatile family of molecules which have a wide range of potential applications in many domains of life. This new and important book gathers the latest research from around the globe in the study of this dynamic field and focuses on related topics such as: organometallic compounds in therapy, toxicology of organotins in marine organisms, photophysics of group IV metallocenes and others.
