Chalcogen bond (ChB) is a relevant supramolecular tool in designing the secondary coordination sphere of metal complexes, contributing to the improvement of functional properties of materials. It is a noncovalent interaction between the electron density deficient region of a chalcogen atom and a nucleophilic site in the same or another molecular entity.
The chalcogen bond (ChB) is defined as a noncovalent interaction between the electron density deficient region (so-called as sigma or pi hole) of a covalently bonded chalcogen atom and a nucleophilic (Nu) site in the same (intramolecular) or another (intermolecular) molecular entity: R-Ch center dot center dot center dot Nu [Ch = O, S, Se or Te; R = C, Pn (pnictogen), Ch, metal, etc.; Nu = lone pair possessing Ha, Ch, Pn or metal atom, pi-system, anion, radical, etc.]. Like in halogen (Ha) and pnictogen (Pn) bonds, the bond parameters (strength, high directionality and tunability) make ChB a relevant supramolecular tool in the design of the secondary coordination sphere of metal complexes, which concerns an important synthetic strategy in the improvement of functional properties of materials. In this review we discuss/illustrate several relevant examples, taken from the Cambridge Structural Database, in which ChB plays a crucial role in the decoration of the secondary coordination sphere of coordination compounds, controlling molecular conformation, packing and aggregation of tectons, as well as formation of supramolecular 0D aggregates, 1D chains, 2D layers, 3D frameworks, etc. (c) 2022 Elsevier B.V.
