"A cyclopentadienyl complex is a coordination complex of a metal and cyclopentadienyl groups (C 5H 5, abbreviated as Cp ). Cyclopentadienyl ligands almost invariably bind to metals as a pentahapto (η -) bonding mode. The metal–cyclopentadienyl interaction is typically drawn as a single line from the metal center to the center of the Cp ring. " - Cyclopenta ring
