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 ...

Amine–carboxylate supramolecular synthon in pharmaceutical cocrystals
CrystEngComm, 2018Four novel pharmaceutical cocrystals of l-proline were obtained via combined virtual and experimental screening. The results confirm that an amine–carboxylate supramolecular synthon can be used for pharmaceutical cocrystal design.

Gold⋯π aryl interactions as supramolecular synthons
CrystEngComm, 2009Au⋯π interactions whereby the electron-rich π-system of C6-aromatic rings interact with gold are shown to exist in the crystal structures of both gold(I) and gold(III) complexes, and have been revealed to occur between neutral/neutral, cationic/cationic, and cationic/anionic systems.

Pb···π Aryl Interactions as Supramolecular Synthons
Australian Journal of Chemistry, 2010A survey of lead (Pb) structures containing Pb···π aryl interactions has been conducted. Such contacts usually lead to zero- or one-dimensional aggregates with rare examples of two- and three-dimensional architectures. The Pb···π aryl interactions are found only in crystal structures containing lead(ii) centres and arise as a result of electron ...

Synthesis of Multitopic Verdazyl Radical Ligands. Paramagnetic Supramolecular Synthons
Organic Letters, 2004[structure: see text] The syntheses of several verdazyl radical and diradicals containing pyridine-based multitopic coordination sites are described. These compounds were designed to be paramagnetic analogues of oligopyridine metallosupramolecular building blocks.

Langmuir, 2009
Following the supramolecular synthon approach, a combinatorial library comprising 35 organic salts derived from 7 dicarboxylic acids (malonic-, succinic-, adipic-, L-tartaric-, maleic-, phthalic-, and isophthalicacid) and 5 primaryalkyl amines Me-(CH2)n-NH2 (n = 11-15) was prepared and scanned for gelation.

Multinuclear Silver Ethynide Supramolecular Synthons for the Construction of Coordination Networks
Chemistry – An Asian Journal, 2007AbstractThe invariant appearance of the μ8 coordination mode for the C42− dianion in its silver(I) complexes, with four silver(I) atoms attached to each terminal ethynide moiety, implies that the Ag4⊂CCCC⊃Ag4 species may be considered as a new type of supramolecular synthon for the construction of 1D, 2D, and 3D coordination polymers.
