Investigations of Metal-Coordinated Peptides as Supramolecular Synthons
The Journal of Organic Chemistry, 2006This 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, 2010The 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 in phenol–isonicotinamide adducts
CrystEngComm, 2003Molecular 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
1998The 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.

Cooperative effects on the formation of supramolecular synthons of thiohydantoin derivatives
Journal of Computational Methods in Sciences and Engineering, 2014In this paper we study the manifestations of cooperative effects in the formation of supramolecular synthons observed in some thiohydantoin derivatives crystals. Energetic and structural properties were analyzed from the fully optimized clusters employing a DFT/B3LYP level of calculations, which reproduce the main features of the stereochemistry and ...

Supramolecular Synthons: Validation and Ranking of Intermolecular Interaction Energies
Crystal Growth & Design, 2012Building upon Desiraju’s concept of a supramolecular synthon, we have calculated cohesive energies and thermal stabilities of molecular systems related to the proposed synthons. The method employed is PIXEL, which allows reliable and extensive mapping of intermolecular surfaces. Comparisons with accurate ab initio calculations are included.

Supramolecular Synthons in Bumetanide Cocrystals and Ternary Products
Crystal Growth & Design, 2017A novel design strategy for cocrystals of the diuretic sulfonamide drug bumetanide (BUM) with carboxamides is reported based on reliable supramolecular synthons. Binary cocrystals of BUM with pyridine carboxamides, pyridones, and cytosine were obtained by solvent-assisted grinding followed by solution crystallization.
