A Structural Approach to the Strength Evaluation of Linear Chalcogen Bonds

open access: yesMolecules, 2023
The experimental structural features of chalcogen bonding (ChB) interactions in over 34,000 linear fragments R–Ch⋯A (Ch = S, Se, Te; R = C, N, O, S, Se, Te; A = N, O, S, Se, Te, F, Cl, Br, I) were analyzed.

Matere Bonds vs. Multivalent Halogen and Chalcogen Bonds: Three Case Studies

open access: yesMolecules, 2022
The term matere bond has been recently used to refer to an attractive noncovalent interaction between any element of group 7 acting as an electrophile and any atom (or group of atoms) acting as a nucleophile.

Chalcogen–Chalcogen Bonding Catalysis Enables Assembly of Discrete Molecules [PDF]

open access: yesJournal of the American Chemical Society, 2019
Despite the observation of noncovalent interactions between chalcogen atoms in X-ray crystal structures, catalysis that harnesses the power of such chalcogen-chalcogen bonding interactions to produce advanced molecules remains an unresolved problem. Here, we show that a class of extraordinary chalcogen-bonding catalysts enables assembly of discrete ...
