  • Descrição: The molecular and electronic structures of some hypothetical sandwich-type π-complexes of transition metals with fullerene C 60 were modeled. The M-C 60 bonds in η 5 -C 60 MCp + complexes (M = Fe, Ru, Os) are less strong than the M-Cp bonds in ferrocene, ruthenocene, and osmocene, respectively. The η 6 -C 60 MC 6 H 6 complexes (M = Cr, Mo, W) should be less stable than their classical analogs (C 6 H 6 )M(C 6 H 6 ). The coordination of a metal atom with the fullerene at its pentagonal face is more energetically favorable than at a hexagonal face.
