Does Oxygen Feature Chalcogen Bonding?

Di: Stella

Two oxygen atoms bind together with a covalent double bond to form an oxygen molecule (O2), also known as dioxygen. This type of molecule that is made up of two atoms of Two of the pyridine nitrogen atoms have lone electron pairs pointing toward the water’s oxygen atom, and the team found comparatively short distances between those Dichalcogenides are important intermediates in the catalytic cycle of the Glutathione peroxidase (GPx), the enzyme regulating the level of reactive oxygen species

There are views prevalent in the noncovalent chemistry literature that i) the O atom in molecules cannot form a chalcogen bond, and ii) if formed, this bond is very weak. We

Divalent sulfur (S) forms a chalcogen bond (Ch-bond) via its σ-holes and a hydrogen bond (H-bond) via its lone pairs.

Thus, the Ch⋯Nu chalcogen bonding becomes weaker as the R–Ch⋯Nu assignment is moved away from linearity. Like other σ-hole bonds, both strength and Highlights • Chalcogen bonding influences the structure and properties of functional materials. • Examples include charge transfer salts, neutral heterocyclic free radicals, and Density functional calculations of the potential energy surface for the reactions 2Cl + 1O3 → 2ClO +3O2 and 2ClO + 3O → 2Cl + 3O2 have been carried out using the
