  • Although it is a fundamental property of many small molecules, chirality is not widely exploited in materials applications as its benefits are not widely recognized — indeed, the need for stereoselective synthesis may be seen as a disadvantage. In this Review, we highlight recent research in which chirality has had an enabling impact in technological applications.

  • Computational and spectroscopic studies of molecular lanthanide complexes have implicated 4f orbitals in metal–ligand bonding interactions. Now, a comparative study of isostructural d-block, actinide and lanthanide complexes has shown that 4f-orbital covalency enables ring-opening isomerization in a Ce(IV)–cyclopropenyl complex in the solid state, a reaction not observed for the other complexes studied.

  • Diatomic actinide molecules are ideal models for studying rare multiple-bond motifs. Here, the authors report host-guest structures of metastable charged U≡N diatoms confined in fullerene cages and stabilized by coordinative electron transfer.

  • While metal–carbon double bonds are common in transition metal chemistry and catalysis, unsupported uranium–carbon double bonds remain highly challenging to prepare. Here, the authors stabilize and characterize a U=C=U cluster containing unusually short, unsupported double bonds inside an Ih(7)-C80 fullerene cage.

  • Trivalent lanthanides are typically described using an ionic picture that leads to localized magnetic moments. Here authors show that the “textbook” description of lanthanides fails for Pr4+ ions where the hierarchy of single-ion energy scales can be tailored to explore correlated phenomena in quantum materials.

  • Actinide-ligand bonds with high multiplicities remain poorly understood. Here, the authors investigate covalency in actinide complexes and identify terminal O and N ligands that are triply to quadruply bonded to the actinide, facilitated by electrostatic, steric, and covalent interactions.

  • Ce(IV) organometallic compounds are rare due to Ce(IV) being a powerful oxidant. Herein, the authors explore the covalency of a pair of organocerium complexes bearing a Ce(IV)-C(aryl) bond and examine their structure by NMR spectroscopy, X-ray diffraction analysis, and computational calculations.

  • Enhanced covalency is achieved for a curium complex with curium–sulfur bonds by subjecting the compound to high pressures, indicating that pressure can be used to tune covalency in actinide compounds.

  • Understanding the electronic structure of the actinide series is critical for advancing the nuclear fuel cycle. Here, the authors explore a series of isostructural An(COTbig)2 (An = Th, U, Np, Pu) complexes with clam-shell geometries, where structural and electronic characterization highlights the impact of f-orbital contributions in actinide bonding.
