  • Aromaticity is a ubiquitous concept in organic chemistry yet it is less widespread for inorganic species. Now the cluster [(CpRu)3Bi6]–, obtained as part of a soluble salt, has been shown to exhibit aromatic behaviour referred to as φ-type, owing to a highly regular {Bi6} substructure causing a non-localizable molecular orbital of \(f_{z^3}\)-like symmetry.

  • Low-valent zinc clusters, though exceedingly rare, are appealing synthetic targets because there is evidence that they may show unconventional chemical and physical behavior. Here, the authors obtain a large heterometallic zinc-bismuth cluster anion and discover that it bears a metalloid {Zn12} core with four-center bonding and essentially zero-valent character.

  • A wide variety of organic and inorganic compounds show π-aromaticity, yet for all-metal systems it has remained restricted to compounds with three to five atoms. Now, the anionic cluster [Th@Bi12]4− has been shown to exhibit π-aromaticity, with a significant ring current despite relying on the delocalization of only two π-electrons.
