Ferrocene based organometallic gelators: a supramolecular synthon approach
Soft Matter, 2011The supramolecular synthon namely primary ammonium dicarboxylate (PAD) synthon has been exploited to generate a new series of salt based low molecular weight gelators (LMWGs) derived from ferrocenedicarboxylic acid (FDCA) and primary amines Me–(CH2)n–NH2 (n = 3–15).

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.

Conserved hydrogen-bonded supramolecular synthons in pyridinium tetrachlorometallates
CrystEngComm, 2004The crystal and molecular structures of the pyridinium tetrahalometallates, [Hpy]2[CoCl4] and [Etpy]2[CoCl4], have been determined and compared with those of other pyridinium tetrahalometallates and 4,4'-bipyridinium perhalometallates. The pyridinium cation in [Hpy]2[CoCl4] uses its heterocyclic N–H and 4-positioned C–H moieties to form bifurcated ...

THEORETICAL STUDIES OF THE SUPRAMOLECULAR SYNTHON BENZENE � � � HEXAFLUOROBENZENE
Journal of Physical Organic Chemistry, 1997The benzene · · · hexafluorobenzene stacking interaction was evaluated at several levels of theory. At the MP2/6–31G** level, it is estimated that the interaction is stabilizing by approximately 3.7 kcal mol−1. Lower levels of theory perform poorly on this system. This is a fairly strong non-covalent interaction, suggesting this motif may be a valuable

A Supramolecular Synthon for H-Bonded Transition Metal Arrays
Inorganic Chemistry, 1999The heterocycle melamine appended to a 14-membered polyazamacrocyclic copper(II) complex ring exhibits a strong propensity for ordered arrays driven by H-bonding forces. In this work, the X-ray crystal structures of three distinctly different arrays based on the same macrocyclic complex are reported, comprising cocrystals with barbituric acid (a sheet ...

Four‐Center Nodes: Supramolecular Synthons Based on Cyclic Halogen Bonding
Chemistry – A European Journal, 2019AbstractThe isocyanide trans‐[PdBr2(CNC6H4‐4‐X′)2] (X′=Br, I) and nitrile trans‐[PtX2(NCC6H4‐4‐X′)2] (X/X′=Cl/Cl, Cl/Br, Br/Cl, Br/Br) complexes exhibit similar structural motif in the solid state, which is determined by hitherto unreported four‐center nodes formed by cyclic halogen bonding.

N-terminal protein recognition by supramolecular synthons
This research investigate the biomolecular recognition capabilities of WPCTX, an anionic phosphocavitand. Cocrystallization trials of WPCTX and two different model proteins were performed. X-ray crystallography was used to elucidate the structures of the resulting crystals. NMR spectroscopy was used to characterize the protein – macrocycle interactionsopenaire +1 more source
