But supramolecular patterns in crystals resemble the aerial patterns formed by skydivers in that properties of the group are distinct from those of the individual constituents. In this sense, a crystal of an organic compound is the perfect supermolecule and crystal engineering, which is the deliberate design of crystal structures of organic compounds, is the supramolecular equivalent of organic synthesis. By defining a “supramolecular synthon” as a building block that incorporates both chemical and geometrical features of sets of intermolecular interactions, the conceptual similarity between crystal engineering and classical organic synthesis is uncovered. This striking parallel is discussed by G. R. Desiraju on pp. 2328. Citing Literature Volume34, Issue21November 17, 1995 RelatedInformation
