Stable 1,3,2-Benzodithiazolyl Radicals: Modification of Reactivity, Crystal Packing, and Solid State Magnetic Properties by Fluorination. [PDF]

ChemistryOpen
Fluorination reduces solid‐state thermal stability of 1,3,2‐benzodithiazolyl radicals and modulates crystal structures (e.g., by means of a new supramolecular zip‐synthon) and reactivity, in the latter case toward transformations unknown in the hydrocarbon series but potentially general in the fluorocarbon one.

Perplexing Coordination Behaviour of Potentially Bridging Bipyridyl-Type Ligands in the Coordination Chemistry of Zinc and Cadmium 1,1-Dithiolate Compounds [PDF]

, 2018
The X-ray structural chemistry of zinc and cadmium 1,1-dithiolates (for example, xanthate, dithiophosphate and dithiocarbamate) with potentially bridging bipyridyl-type ligands (for example, 4,40-bipyridine) is reviewed.

Self-assembly and two-dimensional spontaneous resolution of cyano-functionalized [7]helicenes on Cu111 [PDF]

, 2011
Birds of a feather flock together: STM and DFT studies provide the first example of spontaneous chiral resolution of a helicene on a surface. Racemic 6,13-dicyano[7]helicene forms fully segregated domains of pure enantiomers (2D conglomerate) on Cu(111).

Assessment of Computational Tools for Predicting Supramolecular Synthons [PDF]

Chemistry, 2021
The ability to predict the most likely supramolecular synthons in a crystalline solid is a valuable starting point for subsequently predicting the full crystal structure of a molecule with multiple competing molecular recognition sites. Energy and informatics-based prediction models based on molecular electrostatic potentials (MEPs), hydrogen-bond ...

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

Acta Crystallographica Section A Foundations of Crystallography, 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 Synthon Promiscuity in Phosphoric Acid–Dihydrogen Phosphate Ionic Cocrystals

Crystal Growth & Design, 2022
Approximately 80% of active pharmaceutical ingredients (APIs) studied as lead candidates in drug development exhibit low aqueous solubility, which typically results in such APIs being poorly absorbed and exhibiting low bioavailability. Salts of ionizable APIs and, more recently, pharmaceutical cocrystals can address low solubility and other relevant ...
