Editor’s Collection: Halogen Bonding in Crystal Engineering


We are delighted to share with you our latest collection of recently published articles focusing on Halogen Bonding in Crystal Engineering, handpicked by Chair of the Editorial Board, Pierangelo Metrangolo, Politecnico di Milano, Italy.

The halogen bond is the attractive interaction between an electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity. Since its rediscovery in the early 2000s, the field of halogen bonding has boomed, becoming one of the most used chemical interactions in crystal engineering. This Editor’s collection highlights recent contributions to CrystEngComm that are broadly focused on halogen bonding in crystal engineering. The selection of articles showcases how the field has developed from the design of crystal structures to the development of functional materials. The wide range of halogen bond applications covers phosphorescent materials, pharmaceutical co-crystals and peptides, organic electronics, coordination frameworks, where the halogen bonds either drive the formation of the network, or stabilize it as a secondary interaction, or is used to bind hosted guests. Halogen bonding has become a mature field of research but its rediscovery has sparked interest towards other lesser known interactions, which are anticipated to become more prominent in the future, such as chalcogen, pnictogen, and tetrel bonds.

All of these articles are free to access until June 30th 2021 and we hope you enjoy reading them.

We also invite you to submit your research to CrystEngComm to give your work the global visibility it deserves.
