Molecules, 2023 Charge-shift (CS) bonding is a new bonding paradigm in the field of chemical bonds. Our recent study has revealed that certain Cu/Ag/Au-bonds display both CS bonding and ω-bonding characters. In this investigation, we extend our study to halogen bonding.

Astatine Facing Janus: Halogen Bonding vs. Charge-Shift Bonding
Molecules, 2021 The nature of halogen-bond interactions was scrutinized from the perspective of astatine, potentially the strongest halogen-bond donor atom. In addition to its remarkable electronic properties (e.g., its higher aromaticity compared to benzene), C6At6 can

Direct arylation reaction of heteroarenes mediated by photoinduced electron transfer
Journal of Photochemistry and Photobiology, 2023 Electron donor–acceptor (EDA) complexes are interesting chemical species that function as molecular complexes. In this context, chemists have actively studies the use of halogen bonding as a noncovalent interaction in photochemistry.

Combining high-resolution scanning tunnelling microscopy and first-principles simulations to identify halogen bonding [PDF]
, 2020 Scanning tunnelling microscopy (STM) is commonly used to identify on-surface molecular self-assembled structures. However, its limited ability to reveal only the overall shape of molecules and their relative positions is not always enough to fully solve ...

Type II halogen···halogen contacts are halogen bonds [PDF]
IUCrJ, 2013 Cl/Br/I alternative substitutions in a series of dihalophenols indicate that type I and type II halogen···halogen contacts have different chemical nature. Only the latter ones qualify as true halogen bonds, according to the recent IUPAC definition.

Cooperativity of halogen bonds – enhancing halogen-bond donating ability of halogenated pyridines through halogen bonding with N-haloimides [PDF]
Acta Crystallographica Section A Foundations and Advances, 2018 N-halogenated imides, common halogenating agents in organic synthesis, have recently been marked as extremely strong halogen donors. In previous studies we have demonstrated that N-halogenated succinimides form extremely short XBs with halogen bond energies between 20 and 60 kJ mol–1, depending on the pyridine basicity and the halogen atom. In light of
