WebHalogen bonds occur when a halogen atom is electrostatically attracted to a partial negative charge.Necessarily, the atom must be covalently bonded in an antipodal σ-bond; the electron concentration associated with that bond leaves a positively charged "hole" on the other side. Although all halogens can theoretically participate in halogen bonds, the σ-hole shrinks if …
