Exocyclic coordination of the η3-fluorenyl, η3-cyclopenta[def]phenanthrenyl and η3-8,9-dihydrocyclopenta[def]phenanthrenyl anions: X-ray crystal structures, NMR fluxionality and theoretical studies
Abstract
The novel complexes IndMo(η3-Flu)(CO)2
(Flu = fluorenyl), (η5-Ind)Mo(η3-cpp)(CO)2
(cpp = cyclopenta[def]phenanthrenyl) and (η5-Ind)Mo(η3-H2cpp)(CO)2
(H2cpp = 8,9-dihydrocyclopenta[def]phenanthrenyl) have been prepared and their molecular structures determined. X-Ray crystallographic studies show an exocyclic η3-coordination for the Flu, cpp and H2cpp
