Figure 1

Left-center: An illustration of the isolobal relationship between the frontier orbitals of Cp2M and (RN)2M complexes. The given orbital occupation corresponds to a d0 electron configuration. The charges p and q are related by p = q + 2 for isoelectronic complexes of elements from the same group. Center-right: Molecular orbital interaction scheme depicting the symmetry and relative energy considerations for forming π-loaded four-coordinate bis(imido) complexes by using a π-donating bidentate ligand.
