Abstract

original image

The same number of valence orbitals and valence electrons, as well as valence orbitals of similar symmetry and energy, results when the cyclopentadienyl ligand in [(η5-C5R′5)M] is substituted by an imido ligand NR and the metal atom by an isoelectronic M′ of the next higher group (see the series below). Through coupling of the imido complex fragments with [CpFe(CO)2], the characteristic bonding capability of each entity can be determined.
