A soft embrace for U : Replacement of C 5 Me 5 by the soft PNP pincer ligand is a successful strategy to promote new reactivities and support new structures for the actinide series (see picture, py–O=pyridine‐ N ‐oxide). The specific electronic and steric properties of the PNP ligand enable access to previously unreported structures not available for the C 5 Me 5 ligand set and support not only low‐valent uranium but also the high‐valent uranium(VI) ion.
