摘要：

Amidato-N ligands are normally viewed as classic, strongly a-donating, innocent ligands. However, when coordinated to high-valent transition metal centers, tetraamidomacrocyclic ligands are often substantially noninnocent, i.e., exhibit radical character involving the amido pi-systems. Even the so-called MAC* ligand, generally considered to be an innocent ligand, is noninnocent in several of its known complexes. (c) 2006 Elsevier Inc. All rights reserved.
