Peter Politzer, Jane Murray and Timothy Clark review sigma-hole bonding in their recent PCCP Perspective and its contribution to the understanding of the halogen bond and other non-covalent interactions. They detail the historic background of the concept of sigma-hole bonding from both experimental and theoretical perspectives, and present the most recent theoretical findings on the fascinating character of this class of molecular interactions.
