Illustrated Glossary of Organic Chemistry

Ferrocene: An organometallic compound featuring Fe2+ cation bonded to each carbon of two cyclopentadienyl anion (Cp) rings. This bonding is shown as a line between the iron atom and the center of the ring. Sometimes called a "sandwich compound" because of its structure: an Fe2+ cation sandwiched between two slices of cyclopentadienyl anion bread.
