Bonding: | The bonding in π-organometallics must be considered using LCAO MO theory because the normal rules of valency break down. For example, is the valency of the Fe(II) ion in the metallocene in ferrocene, Fe(C5H5)2? Is the iron 2 valent or 10 valent? ![]() The hapto nomenclature, ηx, where the hapacity (Wikipedia) gives the number of conjugated p orbitals which ligate to a metal, rather than the number of electrons. |

Charge: | Complexes may be negatively charged, positively charged or they may be neutral. | ||||||||||||||||||||||||||||||
Chemistry: | There is a very extensive π-heavy metal chemistry known: all heavy metals are known to form π-organometallic compounds.
