Molecular complexes with slow magnetic relaxation, mainly based on 3d and 4f metals, are the subject of intensive research in diverse fields such as high-density memory recording, quantum information processes, magnetocaloric refrigeration, and spintronic applications. The use of actinide ions, which have an unfilled 5f shell that could carry a large ligand-field anisotropy barrier together with a significant exchange interaction, has been envisaged. Recent advancements in this field are reviewed in the perspective by Nicola Magnani on page 755 (DOI: 10.1002/qua.24656), with particular emphasis on some presently unresolved challenges.
