Supramolecular synthons in crystal engineering. Structure simplification, synthon robustness and supramolecular retrosynthesis

Chemical Communications, 1996
The analogy between crystal engineering and traditional organic synthesis is outlined with reference to a family of crystal structures which incorporate iodo⋯nitro and carboxyl dimmer supramolecular synthons.

Investigations of Metal-Coordinated Peptides as Supramolecular Synthons

The Journal of Organic Chemistry, 2006
This article describes the synthesis and controlled assembly of four model biological-hybrid scaffolds via coordination of a metal complex to four new tripeptides. Each model tripeptide investigated has either a central pyridyl glycyl or a pyridyl alanyl residue between two terminally protected glycines.

Development and boundaries in the field of supramolecular synthons

CrystEngComm, 2010
The theme of supramolecular synthons runs through all disciplines of crystal engineering. The concept of supramolecular synthons has received ever increasing attention in various fields since it was defined and introduced in 1997. This trend is manifest in the exploding number of articles published, and not only in the specialised journals, Crystal ...

Supramolecular synthons and crystal structure prediction of organic compounds [PDF]

Acta Crystallographica Section A: Foundations and Advances, 2004
The strategy taking into account regularities of crystal structure formation and results of theoretical crystal structure prediction has been proposed as a tool for crystal engineering. The role of the symmetry of the supramolecular associates (synthons) in the symmetry of the crystal structure is suggested.

Supramolecular synthons in phenol–isonicotinamide adducts

CrystEngComm, 2003
Molecular complexes of four phenols (hydroquinone, resorcinol, phloroglucinol and 4-hydroxybenzoic acid) with isonicotinamide are characterized by X-ray diffraction. (Hydroquinone)0.5·(isonicotinamide) 1 and (resorcinol)·(isonicotinamide)22 have tapes of O–H⋯N and amide N–H⋯O dimer synthons.

Supramolecular Synthons and Pattern Recognition

1998
The aims of crystal engineering are the understanding of intermolecular interactions and their application in the design of crystal structures with specific architectures and properties. In general, all types of crystal structures may be considered but this article is limited to organic molecular solids.
