Abstract

Metal sandwich complexes of the classical type M(CnHn)2 and related structural analogs are characterized by a sandwich-like coordination of one central atom by its ligands. This structural principle has been extended in recent years now that di- and tri-nuclear sandwich-type complexes have become accessible. The best-known representatives are the triple-decker sandwich complexes. A survey of this topical field is presented in this report, which also underlines the utility of kinetic and mechanistic studies for the development of new synthetic pathways in organometallic chemistry.
