  • The bonding order of multiply bonded main-group elements is conventionally thought to be limited to triple bonds. Now, using high-level theoretical methods, it is shown that C2 and its isoelectronic molecules CN+, BN and CB− are quadruply bonded, featuring not only one σ - and two π-bonds, but also one weak ‘inverted’ bond.

  • Intermolecular non-polar H···H interactions between polyhedrane molecules may be as attractive as classical hydrogen bonds. A theoretical study identifies the chemical and structural factors that favour such attractive interactions.

  • The two established models of chemical bonding, covalent and ionic, do not accurately describe all forms of bonds. This article explains how 'charge-shift' bonds — with a large covalent–ionic resonance interaction energy — are a third type of bond, and discusses some examples.
