  • Boron is known to form a wide variety of molecular structures. Here, the authors observe the highly symmetric cobalt-centered boron drum-like structure of CoB16−, characterized by photoelectron spectroscopy and ab initio calculations, in which the cobalt atom is sixteen-coordinate.

  • Fundamental understanding of gold–carbon bonding in homogeneous catalysts is vital for improved catalyst design, although spectroscopic information is limited. Here, the authors probe the bonding in gold–alkyne complexes using a combination of photoelectron spectroscopy and ab initiocalculations.

  • Unlike carbon, boron is unable to form graphene-type structures, although variants with hexagonal holes have been suggested. Here the authors provide experimental evidence for the viability of such atom-thin boron sheets on the basis of a hexagonal vacancy discovered in a 36-atom planar boron cluster.

  • A combined theoretical and experimental approach has been used to investigate the structure and bonding of an all-boron cluster (B19−). Calculations suggest that the minimum energy structure is a near-planar one — in which a pentagonal B6 unit is encircled by a larger B13 ring — possessing two concentric aromatic π systems.

  • Main-group analogues to fullerene-C60 have been predicted theoretically many times. Now, B40− has been observed using photoelectron spectroscopy and, with its neutral analogue, B40, confirmed computationally. In contrast to fullerene-C60, the all-boron fullerene (or borospherene) features triangles, hexagons and heptagons, bonded uniformly by delocalized σ and π bonds over the cage surface.

  • A method that uses intersource correlograms measured by a single-station seismograph to constrain planetary interiors is presented. Applied to Mars, it measures a core radius of 1,812 ± 20 km, consistent with InSight direct-seismic-wave measurements. Such a method is useful in planetary exploration where the deployment of a full network of seismographs is unlikely.

  • The most common oxidation state for lanthanides is +3. Here the authors use photoelectron spectroscopy and theoretical calculations to study half-sandwich complexes where a lanthanide center in the oxidation state +1 is bound to an aromatic wheel-like B82- ligand.

  • Borospherenes are the boron-based analogs of fullerene cages. Here, the authors report a class of Ln3B18– metallo-borospherenes with unusual spherical trihedron geometry, in which the lanthanide atoms surprisingly form a part of the cage surface.

  • The unusual electronic characteristics of boron atoms lead boron clusters to adopt a wide variety of structural arrangements, most of which are 2D. This Perspective discusses the possibility of expanding the range of boron-based 2D structures by metal doping, as well as the use of the resulting clusters for conceptualizing metalloborophenes.

  • Acute-on-chronic liver failure (ACLF) is a unique clinical entity that causes confusion amongst clinicians because no clear definition or standardized clinical features have been agreed worldwide. A recent comprehensive study provided an evidence-based definition and addressed its clinical features in patients with ACLF who have cirrhosis with acute decompensation.

  • Despite its electron deficiency, boron can form multiple bonds with a variety of elements, but such bonds between boron and main-group metal elements are relatively rare. Here, the authors characterize boron–lead multiple bonds in PbB2O- and PbB3O2- produced by laser vaporization.
