Open AccessChemical design of electronic and magnetic energy scales of tetravalent praseodymium materials
Lanthanides in the trivalent oxidation state are typically described using an ionic picture that leads to localized magnetic moments. The hierarchical energy scales associated with trivalent lanthanides produc...

Open AccessA charged diatomic triple-bonded U≡N species trapped in C82 fullerene cages
Actinide diatomic molecules are ideal models to study elusive actinide multiple bonds, but most of these diatomic molecules have so far only been studied in solid inert gas matrices. Herein, we report a charge...

Open AccessIsolation and characterization of a covalent CeIV-Aryl complex with an anomalous 13C chemical shift
The synthesis of bona fide organometallic CeIV complexes is a formidable challenge given the typically oxidizing properties of the CeIV cation and reducing tendencies of carbanions. Herein, we report a pair of co...

Compression of curium pyrrolidine-dithiocarbamate enhances covalency
Curium is unique in the actinide series because its half-filled 5f 7 shell has lower energy than other 5f n configurations, rendering it both redox-inactive and resistant to forming chemical bonds that engage the...

Open AccessA diuranium carbide cluster stabilized inside a C80 fullerene cage
Unsupported non-bridged uranium–carbon double bonds have long been sought after in actinide chemistry as fundamental synthetic targets in the study of actinide-ligand multiple bonding. Here we report that, uti...

Open AccessTargeted radionuclide therapy with astatine-211: Oxidative dehalogenation of astatobenzoate conjugates
211At is a most promising radionuclide for targeted alpha therapy. However, its limited availability and poorly known basic chemistry hamper its use. Based on the analogy with iodine, lab...
