  • Möbius aromaticity extends the concept beyond Hückel systems, but examples are quite uncommon and typically display twisted topologies. Here the authors describe planar Möbius aromatic complexes, which contain 16 and 18 valence electron osmium centres.

  • Molecular SiO2 and other simple silicon oxides have remained elusive despite the importance of silicon dioxide materials in advanced electronic devices. Clusters Si2O3 and Si2O4 have now been experimentally realized by direct oxidation of a carbene-stabilized disilicon using N2O and O2, respectively.

  • Pentalyne — a bicyclic anti-aromatic molecule that contains a strained five-membered ring — is a challenging synthetic target. Incorporation of an osmium centre has been shown to stabilize such features and enable the preparation of two osmapentalyne derivatives. Despite featuring the smallest angles observed so far at a carbyne moiety, these molecules benefit from Möbius aromaticity and reduced ring strain.
