==Structure and bonding==
The iron atom in ferrocene is normally assigned to the +2 oxidation state, as can be shown using [[Mössbauer spectroscopy]]. Each cyclopentadienyl (Cp) ring is then allocated a single negative charge, bringing the number of π-electrons on each ring to six, and thus making them [[aromaticity|aromatic]]. These twelve electrons (six from each ring) are then shared with the metal ''via''
 [[hapticity|haptic]] covalent bonding, which, when combined with the six ''d''-electrons on Fe<sup>2+</sup>, results in the complex having an [[18-electron rule|18-electron]], [[noble gas]] electron configuration.
