[email protected] Edited by A. D. Bond, University of Copen- In the last few decades, supramolecular chemistry has been at the forefront of hagen, Denmark chemical research, with the aim of understanding chemistry beyond the covalent bond. Since the long-range periodicity in crystals is a product of the directionally Keywords: intermolecular interactions; crystal specific short-range intermolecular interactions that are responsible for engineering; self-assembly; halogen bonding; molecular assembly, analysis of crystalline solids provides a primary means to polymorphism; kinetic assembly; coordination
