It is formed by the deprotonation of cyclopentadiene. The cyclopentadienyl anion is a ligand which binds to a metal in organometallic chemistry. [2] The first salt with this anion, potassium cyclopentadienide, was prepared by Johannes Thiele in 1901 [3] but there wasn't much interest in the topic until the discovery of ferrocene in the 1950s.

All 5 carbon atoms of a Cp ligand are bound to the metal in the vast majority of M–Cp complexes. This bonding mode is called η5 -coordination. The M–Cp bonding arises from overlap of the five π molecular orbitals of the Cp ligand with the s, p, and d orbitals on the metal. These complexes are referred to as π-complexes.

In this lecture you will learn the following. The cyclopentadienyl ligands. The synthesis and reactivity of metal−cyclopentadienyl complexes. The metal−cyclopentadienyl interaction. Cyclopentadienyl moiety acts as an important “spectator” ligand and is quite ubiquitous in organometallic chemistry.

In C5H5 there are 10 atoms sharing 10 bonds for which we need to assign the electrons in order to find the oxidation numbers. Once you have drawn the lewis diagram for C 5 H 5, you can look at each bond and assign its electrons to the more electronegative species.

Cyclopentadienyl Anion is an aromatic compound having the formula [C5H5]−. It is abbreviated as Cp−. The deprotonation of cyclopentadiene molecules synthesises it. Cyclopentadienyl Anion is a planar cyclic molecule having six π-electrons.
