The term “halogen bonding” is usually taken to mean the non-covalent interaction of a halogen atom X in one molecule with a negative site, such as the lone pair electrons of a Lewis base, in another. X can be chlorine, bromine or iodine, but not (to our knowledge) fluorine, and halogen bonding does not necessarily always occur for the other halogens, particularly chlorine. X can be part of a dihalogen, e.g. Br2, or it may be a substituent on some other molecule, often organic. Thus, halogen bonding can be depicted as R - X ---: B where :B is the Lewis base.
