,Nature of the π-Complex Bond,olecular orbital theory (MOT). Detailed descriptions of these three approaches are given in the standard inorganic texts and are not repeated here. However, some general statements concerning the applicability of these various bonding descriptions for metal π-complexes are noted.

,Spectroscopic and Magnetic Properties of Metal π-Complexes,, and valency of metal π-complexes. In this chapter some of the details of infrared spectroscopy (IR), nuclear magnetic resonance (NMR), mass spectra, Mössbauer spectroscopy, magnetic susceptibility, and oxidation state are discussed in terms of the characterizations of metal π-complexes.

History, Classification, and Nomenclature,s. It is now known that a large number of both molecules and ions such as monoand diolefins, polyenes, arenes, cyclopentadienyl ions, tropylium ions, and π-allylicions can form metal π-complexes with transition metal atoms or ions.

,Preparation of Metal π-Complexes,reparation most frequently used are substitution, elimination, cyclization, ligand or metal exchange, σ-π rearrangements, and redistribution reactions. Examples of these methods are illustrated in this chapter. The equations presented are not necessarily complete, since the emphasis is placed not on

,Reactions of Metal π-Complexes,nyl, and π-arene metal—demonstrate distinctly characteristic reactions. π-Cyclopentadienyl complexes (metallocenes) exhibit a high degree of aromaticity and undergo many typical aromatic substitution reactions. The π-arene complexes, on the other hand, do not exhibit a discernible degree of aromatic
