Halogen Bonding Involving CO and CS with Carbon as the Electron Donor

Molecules, 2017
MP2/aug’-cc-pVTZ calculations have been carried out to investigate the halogen-bonded complexes formed when CO and CS act as electron-pair donors through C to ClF, ClNC, ClCl, ClOH, ClCN, ClCCH, and ClNH2.

Crystal structures and Hirshfeld analysis of 4,6-dibromoindolenine and its quaternized salt

Acta Crystallographica Section E: Crystallographic Communications, 2021
4,6-Dibromo-2,3,3-trimethyl-3H-indole, C11H11Br2N, exists as a neutral molecule in the asymmetric unit. The asymmetric unit of 4,6-dibromo-2,3,3-trimethyl-3H-indol-1-ium iodide, C12H14Br2N+·I−, contains one organic cation and one iodine anion.

Evidence for Interfacial Halogen Bonding

Angewandte Chemie International Edition, 2016
AbstractA homologous series of donor–π–acceptor dyes was synthesized, differing only in the identity of the halogen substituents about the triphenylamine (TPA; donor) portion of each molecule. Each Dye‐X (X=F, Cl, Br, and I) was immobilized on a TiO2 surface to investigate how the halogen substituents affect the reaction between the light‐induced ...

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

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.

Halogen bonds in biological molecules [PDF]

Proceedings of the National Academy of Sciences, 2004
Short oxygen–halogen interactions have been known in organic chemistry since the 1950s and recently have been exploited in the design of supramolecular assemblies. The present survey of protein and nucleic acid structures reveals similar halogen bonds as potentially stabilizing inter- and intramolecular interactions that can affect

The Role of Halogen Bonding in Controlling Assembly and Organization of Cu(II)-Acac Based Coordination Complexes

Crystals, 2017
In order to explore the use of non-covalent interactions in the deliberate assembly of metal-supramolecular architectures, a series of β-diketone based ligands capable of simultaneously acting as halogen-bond donors and chelating ligands were synthesized.
