Structural flexibility of halogen bonds showed in a single-crystal-to-single-crystal [2+2] photodimerization

IUCrJ, 2018
Halogen bonds have emerged as noncovalent forces that govern the assembly of molecules in organic solids with a degree of reliability akin to hydrogen bonds.

Halogen-Bonded Co-Crystals of Aromatic N-oxides: Polydentate Acceptors for Halogen and Hydrogen Bonds

Crystals, 2017
Seventeen new halogen-bonded co-crystals characterized by single crystal X-ray analysis are presented from 8 × 4 combinations using methyl-substituted pyridine N-oxides and 1,ω-diiodoperfluoroalkanes. The N−O group in six of 17 co-crystals is monodentate

Probing Halogen Bonds by Scalar Couplings. [PDF]

J Am Chem Soc, 2021
As halogen bonding is a weak, transient interaction, its description in solution is challenging. We demonstrate that scalar coupling constants (J) are modulated by halogen bonding.

Real-space Imaging of the Multiple Halogen Bonds by Ultrahigh-resolution Scanning Probe Microscopy [PDF]

, 2021
Understanding the physical origin of STM/AFM image contrast is of significance for not only promoting surface characterization techniques, but also probing surface nanostructures with the atomic/sub-molecular resolution.

Leveraging Halogen Interactions for a Supramolecular Nanotube [PDF]

, 2023
Supramolcular nanotubes in a single crystal were produced from halogenated macrocycles by balancing hydrogen bonds and halogen interactions. A new iodinated macrocycle was prepared, crystallized, and a bonding analysis was performed to evaluate the ...

Activation of a Metal-Halogen Bond by Halogen Bonding [PDF]

, 2020
In recent years, the non-covalent interaction of halogen bonding (XB) has found increasing application in organocatalysis. However, reports of the activation of metal-ligand bonds by XB have so far been limited to a few reactions with elemental iodine or

In Situ Assessment of Intrinsic Strength of X-I⋯OA-Type Halogen Bonds in Molecular Crystals with Periodic Local Vibrational Mode Theory

Molecules, 2020
Periodic local vibrational modes were calculated with the rev-vdW-DF2 density functional to quantify the intrinsic strength of the X-I⋯OA-type halogen bonding (X = I or Cl; OA: carbonyl, ether and N-oxide groups) in 32 model systems originating from 20 ...
