The Halogen Bond in the Design of Functional Supramolecular Materials: Recent Advances [PDF]

open access: yesAccounts of Chemical Research, 2013
Halogen bonding is an emerging noncovalent interaction for constructing supramolecular assemblies. Though similar to the more familiar hydrogen bonding, four primary differences between these two interactions make halogen bonding a unique tool for ...

Halogen-bonded cocrystallization with phosphorus, arsenic and antimony acceptors

open access: yesNature Communications, 2019
Halogen bonding can be exploited for the design of functional supramolecular materials, but heavier elements that are known to accept a halogen bond remain limited.

Type II halogen···halogen contacts are halogen bonds [PDF]

open access: yesIUCrJ, 2014
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.

The Halogen Bond [PDF]

open access: yesChemical Reviews, 2016
The halogen bond occurs when there is evidence of a net 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. In this fairly extensive review, after a brief history of the interaction, we will provide the reader with a snapshot of ...

“Anti-Electrostatic” Halogen Bonding [PDF]

open access: yesAngewandte Chemie International Edition, 2020
Halogen bonding (XB) is often described as being driven predominantly by electrostatics, and thus adducts between anionic XB donors (halogen-based Lewis acids) and anions seem counter­intuitive. Such “anti-electrostatic” XBs have been predicted theoretically, but there are currently no experimental examples based on organic XB donors. Herein, we report

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

open access: yesAngewandte Chemie International Edition, 2020
Abstract 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 bromine. Herein, we present the activation of metal‐halogen bonds by two

Controlling Topology within Halogen-Bonded Networks by Varying the Regiochemistry of the Cyclobutane-Based Nodes

open access: yesMolecules, 2021
The formation of a pair of extended networks sustained by halogen bonds based upon two regioisomers of a photoproduct, namely rctt-1,3-bis(4-pyridyl)-2,4-bis(phenyl)cyclobutane (ht-PP) and rctt-1,2-bis(4-pyridyl)-3,4-bis(phenyl)cyclobutane (hh-PP), that ...

Intramolecular halogen–halogen bonds?

open access: yesPhysical Chemistry Chemical Physics, 2013
By analysing the properties of the electron density in the structurally simple perhalogenated ethanes, X3C-CY3 (X, Y = F, Cl), a previously overlooked non-covalent attraction between halogens attached to opposite carbon atoms is found. Quantum chemical calculations extrapolated towards the full solution of the Schrödinger equation reveal the complex ...

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

open access: yesIUCrJ, 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.

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

open access: yesMolecules, 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 ...
