==Derivatives and variations==
Many other hydrocarbons can be used instead of cyclopentadienyl. For example, [[indene|indenyl]] can be used in place of the cyclopentadienyl to form bisbenzoferrocene.<ref>B.R. Waldbaum and R.C. Kerber, ''Inorg. Chim. Acta'', 1999, '''291''', 109 - 126.</ref>

The carbon atoms can be replaced by heteroatoms as illustrated by [[Fe(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)(η<sup>5</sup>-P<sub>5</sub>]] and [[Fe(η<sup>5</sup>-C<sub>5</sub>H<sub>5</sub>)(η<sup>5</sup>-C<sub>4</sub>H<sub>4</sub>N)]] ("(contracted; show full)[[pl:Ferrocen]]
