Synthesis and structure of clozapine N-oxide hemi(hydrochloride): an infinite hydrogen-bonded poly[n]catenane

Acta Crystallographica Section E: Crystallographic Communications, 2022
The structure of the title compound, 2C18H19ClN4O·HCl or (CNO)2·HCl (C36H39Cl3N8O2), at 100 K has tetragonal (I4/m) symmetry. The dihedral angle between the benzene rings of the fused ring system of the CNO molecule is 40.08 (6)° and the equivalent angle

Single crystal X-ray structural dataset of 1,2,4-dithiazolium tetrafluoroborate

Data in Brief, 2022
Herein, we present the crystallographic dataset of 1,2,4-dithiazolium tetrafluoroborate. Single crystal X-ray structural analysis evidences that the 1,2,4-dithiazolium ring is almost planar. The 1,2,4-dithiazolium and tetrafluoroborate ions contribute in

Hydrogen bonding penalty upon ligand binding.

PLoS ONE, 2011
Ligand binding involves breakage of hydrogen bonds with water molecules and formation of new hydrogen bonds between protein and ligand. In this work, the change of hydrogen bonding energy in the binding process, namely hydrogen bonding penalty, is ...

Triplet–Triplet Energy Transfer Study in Hydrogen Bonding Systems

CHIMIA, 2015
The 2,6-diiodoBodipy–styrylBodipy hydrogen bonding system was prepared to study the effect of hydrogen bonding on the triplet–triplet-energy-transfer (TTET) process. 2,6-DiiodoBodipy linked with N-acetyl-2,6-diaminopyridine (D-2) was used as the
