Crystal structure of [(2S,3R)-3-hydroxy-3-phenylbutan-2-yl]pyrrolidinium chloride

Abstract

In the title molecular salt, C14H22NO+·Cl−, the pyrrolidinium ring adopts a twisted conformation about one of the N—C bonds. It is oriented at a dihedral angle of 42.0 (1)° with respect to the benzene ring. The torsion angle for the central N—C—C—Car (ar = aromatic) linkage is 163.74 (15)°. In the crystal, the components are linked via N—H...Cl and O—H...Cl hydrogen bonds, forming zigzig chains along the b-axis direction. These chains are connected along the c axis by very weak C—H...π interactions, forming a two-dimensional supramolecular network.
