Halogen Bonding in Two‐Dimensional Crystal Engineering

open access: yesChemistryOpen, 2020
Halogen bonds, which provide an intermolecular interaction with moderate strength and high directionality, have emerged as a promising tool in the repertoire of non‐covalent interactions.

Combining high-resolution scanning tunnelling microscopy and first-principles simulations to identify halogen bonding [PDF]

open access: yesNature Communications, 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 ...

Exploring the role of halogen bonding in iodonium ylides: insights into unexpected reactivity and reaction control [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2023
Halogen bonding is commonly found with iodine-containing molecules, and it arises when Lewis bases interact with iodine’s σ-holes. Halogen bonding and σ-holes have been encountered in numerous monovalent and hypervalent iodine-containing compounds, and ...

Site Selectivity of Halogen Oxygen Bonding in 5- and 6-Haloderivatives of Uracil [PDF]

open access: yesCrystals, 2019
Seven 5-and 6-halogenated derivatives of uracil or 1-methyluracil (halogen = Cl, Br, I) were studied by single crystal X-ray diffraction. In contrast with pure 5-halouracils, where the presence of N-H⋯O and C-H⋯O hydrogen bonds prevents the formation of ...

Enhanced enantioselectivity in halogen-bonding catalysis [PDF]

open access: yesCommunications Chemistry, 2023
Chiral halogen-bonding catalysts have emerged as a new approach towards asymmetric catalysis, but enantioselectivities have thus far remained low. Now, fine-tuning the substrate–catalyst halogen–halogen interactions is shown to significantly enhance ...

On the Importance of Halogen Bonding Interactions in Two X-ray Structures Containing All Four (F, Cl, Br, I) Halogen Atoms

open access: yesCrystals, 2021
This manuscript reports the synthesis and X-ray characterization of two octahydro-1H-4,6-epoxycyclopenta[c]pyridin-1-one derivatives that contain the four most abundant halogen atoms (Ha) in the structure with the aim of studying the formation of Ha···Ha

Halogen Bonding: A Halogen-Centered Noncovalent Interaction Yet to Be Understood

open access: yesInorganics, 2019
In addition to the underlying basic concepts and early recognition of halogen bonding, this paper reviews the conflicting views that consistently appear in the area of noncovalent interactions and the ability of covalently bonded halogen atoms in ...

Complementary, Cooperative Ditopic Halogen Bonding and Electron Donor-Acceptor π-π Complexation in the Formation of Cocrystals

open access: yesMolecules, 2022
This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-N,N-dimethylaminophenylethynylpyridines and the ...

Charge-Shift Bonding Propensity in Halogen-Bonded BXY (B Is a Small Lewis Base H2O or NH3; X and Y Are Halogen Atoms) Complexes: An NBO/NRT/AIM Investigation

open access: yesMolecules, 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.
