The purpose of this Viewpoint is to provide a broad-ranging update of advances in the coordination chemistry of redox-active (noninnocent) 2-aminophenolates, with emphasis on two ligand backbone structural parameters, the average of C–O and C–N (C–O/N) bond distances and Δa values, signifying the degree of bond-length alternation in the six-membered ring, in order to identify the redox level of the coordinated ligands. In the absence of magnetic, spectroscopic, and redox results, it has been established that it is possible to assign the electronic ground state of a coordination complex of 2-aminophenolates with consideration of charge, metal–ligand bond distances, and two very promising ligand backbone structural parameters. From a closer look at the sensitive ligand backbone metrical parameters of a diversified group of about 120 transition-metal complexes, a few very useful generalizations have been made.

在2-氨基酚盐的配合物中分配配体氧化还原水平:结构特征。

该观点的目的是提供广泛的氧化还原活性(非纯)2-氨基酚盐配位化学进展的更新,重点是两个配体主链结构参数,即C–O和C–N的平均值( C-O / N)键距和Δ一个值,表示六元环中键长交替的程度,以鉴定配位体的氧化还原水平。在没有磁性,光谱和氧化还原结果的情况下,已经确定可以考虑电荷,金属-配体的键距以及两个非常有前景的配体来分配2-氨基酚盐配位化合物的电子基态骨架结构参数。通过仔细观察约120种过渡金属配合物的多样化组合的敏感配体主链度量参数,已经做了一些非常有用的概括。
