A description of the bonding of π-conjugated
ligands to a transition metal which involves a synergic process with donation of electrons
from the filled π-orbital or lone electron pair orbital of the ligand into an empty
orbital of the metal (donor–acceptor bond), together with release (back donation)
of electrons from an
nd orbital of the metal (which is of π-symmetry with respect to the metal–ligand axis)
into the empty π*-antibonding orbital of the ligand.
