Unusual bonding patterns in halogen-substituted η5-cyclopentadienyl metal derivatives. The crystal and molecular structure of η5-pentachlorocyclo-pentadienylcyclo-octadienerhodium
Abstract
Localized bonding has been observed in the η5-C5Cl5 ring of the title compound which suggests appreciable contribution from a bonding model where the ring is bonded to the metal by two olefin π-bonds and one σ-alkyl bond.
