Themed collection Halogen Bonding in Supramolecular and Solid State Chemistry

We are delighted to share with you a selection of the papers which will be presented at our Faraday Discussion on Halogen Bonding in Supramolecular and Solid State Chemistry taking place in Ottawa, Canada in July 2017. More information about the event may be found here: http://rsc.li/bonding-fd2017. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the live discussions will be published after the event.

                        

Halogen bonding is a topic which continues to gain increased international attention across the chemical, biochemical, and materials sciences - this non-covalent interaction receiving a formal IUPAC definition only recently. The halogen bond may be considered as a special case of sigma-hole bonding, wherein an electron donor interacts with the electrophilic region of a halogen atom. Within this broader picture, sigma-hole bonding can encompass a range of non-covalent interactions which are named after the atom bearing the electrophilic region, also known as the sigma-hole. Chalcogen bonds and pnicogen bonds have been studied both theoretically and in the solid state, for example.

Most recently, the carbon bond has received attention as a special type of tetrel bond. However, the concept of sigma-hole bonding is clearly poised to take on a broader importance to a wide range of researchers and this Faraday Discussion will unite experimentalists and theoreticians who are pushing the applicability of this broad class of interactions far beyond only the halogens.
