  • By means of low-temperature scanning tunnelling spectroscopy, a heavy fermion material in its superconducting and mixed states can be imaged. Besides probing the superconducting gap symmetry, the measurements also reveal a pseudogap.

  • 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.

  • The chemistry of the post-plutonium actinides is thought to resemble lanthanides in that bonding is primarily ionic. Here, the authors show that a californium(III) complex displays significantly different properties to those predicted for the free ion owing to a second break in actinide periodicity.

  • The coordination environment has a great impact on the electronic structure, bonding and properties of metal complexes. Here the authors report a dinuclear organometallic americium complex that displays unexpectedly ionic Am−N bonding, but enhanced covalency in the Am−C bonds compared to its neodymium analogue.

  • Unlike in the d block, intervalence charge transfer is rare in the 5f block owing to localized valence electrons and poor overlap between metal and ligand orbitals. Delocalization of 5f electrons has now been observed in a Pu(III)/Pu(IV)–pyridinedicarboxylate solid-state compound. It occurs through metal-to-ligand charge transfer with both plutonium centres.
