A DFT overview of high-valent iron, cobalt and nickel tetraamidomacrocyclic ligand (TAML) complexes: the end of innocence?
Amidato-N ligands are normally viewed as classic, strongly sigma-donating, innocent ligands. However, when coordinated to high-valent transition metal centers, tetraamidomacrocyclic ligands are often substantially non-innocent, i.e., exhibit radical character involving the amido pi-systems. Even the so-called MAC* ligand, generally considered to be an innocent ligand, is non-innocent in several of its known complexes.
