Crystal structure and Hirshfeld surface analysis of 2-amino-4-(4-methoxyphenyl)-6-oxo-1-phenyl-1,4,5,6-tetrahydropyridine-3-carbonitrile

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2022
The central tetrahydropyridine ring of the title compound, C19H17N3O2, adopts a screw-boat conformation. In the crystal, strong C—H...O and N—H...N hydrogen bonds form dimers with R22(14) and R22(12) ring motifs, respectively, between consecutive ...

Insights into Thiol–Aromatic Interactions: A Stereoelectronic Basis for S–H/π Interactions [PDF]

open access: yes, 2017
Thiols can engage favorably with aromatic rings in S–H/π interactions, within abiological systems and within proteins. However, the underlying bases for S–H/π interactions are not well understood.

Anion Binding to Resorcinarene-Based Cavitands: The Importance of C–H•••Anion Interactions [PDF]

open access: yes, 2008
Anions rather than cations: While resorcinarenes bind cations through cation-π interactions, methylene-bridged cavitands surprisingly bind anions through C-H⋯anion interactions with the acetal protons at the wider rim (see model of the complex in the ...
