TLDR
In this article, a selected set of halogen-bonded architectures have been discussed, where anions function as halogen bonding acceptors, and their ability to afford a wide variety of supramolecular architectures in a rational and predictable way.Abstract:
This highlight discusses a selected set of halogen-bonded architectures reported in the literature wherein anions function as halogen bonding acceptors. Some of these architectures have been assembled purposefully, others have been obtained serendipitously. This paper is perhaps the first attempt to prove the effectiveness of halogen bonding in anion coordination and anion-templated assembly. A corollary of this attempt is that anions are particularly robust tectons in halogen bonding driven self-assembly processes. The focus here is particularly on halide anions and their ability to afford a wide variety of supramolecular architectures in a rational and predictable way. A brief inventory of other anions and their behaviour in self-assembly processes based on halogen bonding is also given.read more

Halogen Bonding: An Interim Discussion
Peter Politzer,Jane S. Murray +1 more
TL;DR: This discussion addresses the origins of σ holes, the factors that govern the magnitudes of their electrostatic potentials, and the properties of the resulting complexes with negative sites, and points out that σ-hole interactions are not limited to halogens, but can also involve covalently bonded atoms of Groups IV-VI.

Halogen bonding: the σ-hole
TL;DR: In this paper, the authors carried out a natural bond order B3LYP analysis of the molecules CF(3)X, with X = F, Cl, Br and I. The results showed that the Cl and Br atoms in these molecules closely approximate the [Formula: see text] configuration, where the z-axis is along the R-X bond.
