  • Promethium remains the least studied element among the lanthanide series because of its scarcity and radiolytic nature. Here, the authors report two new isostructural 2,2’:6’,2”-terpyridine compounds of 147Pm and 248Cm.

  • Laser spectroscopy measurements of the fermium isotopic chain show a smooth trend in the nuclear size of heavy actinide elements, and diminishing shell effects on the size evolution compared with lighter nuclei.

  • Despite the progression of Actinium-225 (225Ac) radiopharmaceuticals, there is still a limited understanding of Ac coordination chemistry due to its radioactivity, poor availability, and lack of stable isotopes. Here, the authors demonstrate a platform to characterize the solution and solid-state behavior of the longest-lived Ac isotope, 227Ac.

  • Studying how the ligand design influences the bonding of f-block complexes is crucial to control their properties. Here, the authors report the preparation of Bk(III) and Ce(III) complexes featuring a terpyridyl ligand; structural, spectroscopic, electrochemical, and theoretical analysis reveal that the ligand induces unusual bonding by creating a plane of enhanced bond covalency.

  • Chemical experiments on californium are stymied by isotope availability and radioactivity considerations, but are advanced here with synthesis and characterization of an organometallic complex.

  • 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.

  • Lanthanides have been identified as biologically essential metals, crucial in the active sites of alcohol dehydrogenase (ADH) enzymes in methylotrophic bacteria. Here, the authors demonstrate that trivalent actinide ions, including actinium, americium, curium, berkelium, and californium, can substitute lanthanides in ADHs and support bacterial growth.
