innocence: A β‐diketiminate(1−) ligand, formerly thought to be innocent, is shown to be redox‐active: It can undergo one‐electron oxidation to form a neutral π radical stabilized by coordination to a high‐spin NiII ion (see scheme). However, since the change in oxidation state of the ligand does not significantly change intraligand bond lengths, its noninnocence is hidden from X‐ray crystallography
