    • This statement usually applies to classical transition metal complexes with σ-donor ligands, but not to 18-electron complexes of σ-donor/π-acceptor ligands. For the general classification of transition metal complexes, see: Elschenbroich, Ch.; Salzer, A. Organometallics: A Concise Introduction, 2nd ed.; VCH: New York, 1992; p 186.

    • Only ns- and np-orbitals are available in main-group elements, since it seems likely that d-orbitals play little or no valence role in their bonding.

    • ·- can be described as a stable radical. What constitutes a "relatively long lifetime" in the context of the description "persistent"? One definition is that it is sufficient time to allow the radical to be prepared in solution or in the solid state at room temperature under an inert atmosphere and to allow it to be spectroscopically and chemically characterized with conventional techniques. These restrictions require a half-life of the order of minutes. However, as will be seen, several of the new main-group radicals have half-lives of at least several months or are indefinitely stable under such conditions. It seems probable that some of these persistent radicals wil be isolated as stable crystalline species in the future.
