Journal ArticleDOI
The pKBHX Database: Toward a Better Understanding of Hydrogen-Bond Basicity for Medicinal Chemists
TL;DR: This paper reviews hydrogenbond basicity scales in general and introduces the pKBHX scale with a brief thermodynamic discussion on the treatment of polyfunctional compounds and discusses the effects of a medium more polar than the definition solvent CCl4 and changes in the reference HB donor on the p KBHX Scale.
Journal ArticleDOI
Halogen-bond geometry: a crystallographic database investigation of dihalogen complexes
TL;DR: This analysis of halogen-bonded complexes in the solid state reinforces the similarities already known to exist between hydrogen and halogen bonding.
Journal ArticleDOI
Hydrogen-bond acceptor properties of nitriles: a combined crystallographic and ab initio theoretical investigation
TL;DR: The hydrogen-bond ability of nitrogen in X-CN···HO-R systems was investigated using crystallographic data retrieved from the Cambridge Structural Database and via ab initio calculations.
Journal ArticleDOI

TL;DR: The present work shows that an oligothiophene spacer is a viable class of linker for connecting porphyrins, and that a quaterthiophene appended with ethynyl linkages affords a high electronic interaction over a distance as large as 28 A.
Journal ArticleDOI
An enthalpic scale of hydrogen-bond basicity. 4. Carbon pi bases, oxygen bases, and miscellaneous second-row, third-row, and fourth-row bases and a survey of the 4-fluorophenol affinity scale.

TL;DR: The thermodynamics of the O-H...B hydrogen bond has been determined in CCl(4) by FTIR spectrometry for a wide variety of carbon pi bases, oxygen bases, and miscellaneous first- to fourth-row bases, using 4-fluorophenol as a reference hydrogen-bond donor (HBD).
