Chalcogen bonding in materials chemistry
Coordination Chemistry Reviews, 2020Abstract This review examines recent literature in search for evidence of the influence that chalcogen bonding has on the structure and properties of functional materials. Key examples from research on charge transfer salts, neutral heterocyclic free radicals, and paramagnetic coordination compounds are highlighted as intermolecular interactions are ...

Dual Chalcogen–Chalcogen Bonding Catalysis
Journal of the American Chemical Society, 2020The noncovalent S···O bonding interaction is an evolutionary force that has been smartly exploited by nature to modulate the conformational preferences of proteins. The employment of this type of weak noncovalent force to drive chemical reactions is promising yet remains largely elusive.

Chalcogen-Bonding Supramolecular Polymers
The Journal of Organic Chemistry, 2020Exploring unknown supramolecular interacting forces to create novel supramolecular materials is an eternal theme of supramolecular science. Here, we first report a new family of supramolecular polymers formed by unconventional chalcogen-bonding interactions. A class of chalcogen-containing macrocyclic receptors, termed as chalcogena[4]arene (ChA[4], Ch

Chalcogen Bonding: An Overview
Angewandte Chemie International Edition, 2018AbstractIn the last few decades, “unusual” noncovalent interactions like anion‐π and halogen bonding have emerged as interesting alternatives to the ubiquitous hydrogen bonding in many research areas. This is also true, to a somewhat lesser extent, for chalcogen bonding, the noncovalent interaction involving Lewis acidic chalcogen centers.

A Porous Chalcogen-Bonded Organic Framework
Journal of the American Chemical Society, 2021The manner of bonding between constituent atoms or molecules invariably influences the properties of materials. Perhaps no material family is more emblematic of this than porous frameworks, wherein the namesake modes of connectivity give rise to discrete subclasses with unique collections of properties.

Enhancing chalcogen bonding by metal coordination
Dalton Transactions, 2022By exploring the CSD in combination with DFT calculations, we demonstrate that chalcogen bonding interactions are strongly enhanced by metal coordination.

Chalcogen Bond: A Sister Noncovalent Bond to Halogen Bond
The Journal of Physical Chemistry A, 2009A sister noncovalent bond to halogen bond, termed chalcogen bond, is defined in this article. By selecting the complexes H(2)CS...Cl(-), F(2)CS...Cl(-), OCS...Cl(-), and SCS...Cl(-) as models, the bond-length change, interaction energy, topological property of the electron charge density and its Laplacian, and the charge transfer of the chalcogen bond ...

Supramolecular Covalence in Bifurcated Chalcogen Bonding
Chemistry – A European Journal, 2017AbstractSupramolecular interactions are generally classified as noncovalent. However, recent studies have demonstrated that many of these interactions are stabilized by a significant covalent component. Herein, for systems of the general structure [MX6]2−:YX2 (M=Se or Pt; Y=S, Se, or Te; X=F, Cl, Br, I), featuring bifurcated chalcogen bonding, it is ...
