Fig. 8.1 (a) Symmetry matching of the molecular orbitals of the Cp ligands with the atomic
orbitals of the Fe atom in ferrocene. The e 2u orbitals of the Cp ligands do not match with any
orbitals of Fe. (b) Schematic molecular orbital diagram for ferrocene. The unoccupied e ∗1g orbitals
of ferrocene have antibonding character

of CrBz 2 , U(COT) 2 , and
[Ni 2 Cp 3 ] +
structures, as demonstrated in the early study that yielded up to hexa-decker
sandwich complexes by using boron heterocycles instead of Cp [23]. More synthetic
attempts on sandwich compounds have been detailed in the former reviews [24–25],
and then we do not intend to introduce such contributions in this chapter.
