This Perspective highlights the use of chalcogen bonding as a versatile synthon for synthesis, catalysis and construction both organic inorganic materials.
The chalcogen bond (ChB) is defined as a noncovalent interaction between the electron density deficient region (so-called σ or π hole) of covalently bonded atom and nucleophilic (Nu) site in same (intramolecular) another (intermolecular) molecular entity: R–Ch⋯Nu [Ch = O, S, Se Te; R C, Pn (pnictogen), Ch, metal, etc.; Nu lone pair possessing Ha, metal atom, π-system, anion, radical, etc.]. Like halogen (Ha) pnictogen (Pn) bonds, parameters (strength, high directionality tunability) make ChB...

Abstract Intramolecular chalcogen bonding in arylhydrazones of sulfamethizole is strengthened by conjugation the π ‐system a noncovalent five‐membered ring. The S⋅⋅⋅O distance moiety these compounds ranges from 2.698(3) to 2.806(15) Å, which indicates its strong dependence on attached arylhydrazone fragments. Information nature intramolecular bond was afforded DFT calculations.
