WebTools. In organometallic chemistry, a transition metal indenyl complex is a coordination compound that contains one or more indenyl ligands. The indenyl ligand is formally the anion derived from deprotonation of indene. The η 5 -indenyl ligand is related to the η 5 cyclopentadienyl anion (Cp), thus indenyl analogues of many cyclopentadienyl ...
