Cyclopentadienyl complex - Wikipedia
A cyclopentadienyl complex is a coordination complex of a metal and cyclopentadienyl groups (C 5 H − 5, abbreviated as Cp −). Cyclopentadienyl ligands almost invariably bind to metals as a pentahapto (η 5-) bonding mode. The metal–cyclopentadienyl interaction is typically drawn as a single line from the metal center to the center of the ...
Cyclopentadienyl anion - Wikipedia
The cyclopentadienyl anion is a planar, cyclic, regular-pentagonal ion; it has 6 π-electrons (4n + 2, where n = 1), which fulfills Hückel's rule of aromaticity. Each double bond and lone pair provides 2 π-electrons, which are delocalized into the ring.

Cyclopentadienyl Group - an overview | ScienceDirect Topics
The cyclopentadienyl group is perhaps one of the most common and important ligands in the organotransition metal chemistry because it is firmly bound to the metal center and almost inert toward substitution. The cyclopentadienyl groups are strongly electron-releasing and their π–accepting ability is much weaker than that of carbon monoxide.
