The novel (eta(5)-Ind)Mo(eta(3)-Flu)(CO)(2) (Ind = indenyl, C9H7; Flu = fluorenyl, C13H9) can be readily prepared from (eta(5)-Ind)MoCl3(CO)(2) and LiFlu in toluene (90% yield). X-ray crystallographic studies show an exocyclic eta(3) coordination for the fluorenyl ligand, which is also predicted from dft calculations.
