Crystal Structure of 1-(2-Pyridiniomethyl)-2,4-bis(phenylsulfonyl)benzene Chloride Ethanol Solvate

Abstract

1-(2-Pyridiniomethyl)-2'4-bis(phenylsulfonyl)benzene chloride ethanol solvate was studied bysingle crystal X-ray diffraction. The conformation, geometric parameters (bond lengths, bond, torsionangles) of the molecular cation (C24H20NO4S2)+ and an EtOH solvation molecule (which is disordered overthree orientations) were determined. In the crystal structure, the hydrogen bonds are formed with the Cl- anion only; it is involved in two H bonds. The stronger H bond is formed with the PyH hydrogen atom, and the weaker H bond, with the hydroxyl hydrogen atom of the disordered EtOH molecule in any of the three possible positions.
