Interplay between non-covalent interactions in complexes and crystals with halogen bonds

Abstract

Studies on the structure and properties of complexes and crystals with halogen bonding accompanied by different secondary non-covalent interactions are summarized. The signs of halogen bonding are systematized and modern methods and approaches used to provide clear and reproducible estimates of the strength of halogen bonds are analyzed. The halogen bond strength values are compared with the strength of the other non-covalent interactions. The contradictions in the interpretation of the results from different studies of the strength of halogen bond are discussed. The bibliography includes 249 references.
