Etter Revised: Graph‐Set Analysis for Supramolecular Patterns in Molecular Crystals ^*

Abstract

Abstract A modification to Etter's graph‐set notation for hydrogen‐bond patterns in molecular crystals is proposed to enable the classification of supramolecular patterns based on any type of non‐covalent interaction (such as hydrogen, halogen, chalcogen, pnictogen, and tetrel bonding). It is recommended that the modified notation be applied to supramolecular patterns based on interactions other than hydrogen bonds, while retaining the original notation for patterns based solely on hydrogen bonds.
