Definition of the pnictogen bond

Provisional Recommendations are drafts of IUPAC recommendations on terminology, nomenclature, and symbols, made widely available to allow interested parties to comment before the recommendations are finally revised and published in IUPAC’s journal Pure and Applied Chemistry.

Provisional Recommendation Abstract: This recommendation proposes a definition for the term “pnictogen bond”: the term pnictogen bond designates a subset of the attractive interactions between an electrophilic region on a pnictogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity.


Keywords: pnictogen bond, IUPAC Organic and Biomolecular Chemistry Division, IUPAC Physical and Biophysical Chemistry Division, nomenclature, noncovalent interactions, self-assembly, supramolecular chemistry.
