Bis[4-(4-chlorophenyl)-4-hydroxypiperidinium] dipicrate dimethyl sulfoxide solvate

Abstract

The asymmetric unit of the title salt solvate, 2C11H15ClNO+·2C6H2N3O7−·C2H6OS, contains two crystallographically independent 4-(4-chlorophenyl)-4-hydroxypiperidinium cations, two picrate anions and a dimethyl sulfoxide solvent molecule. In each cation, the piperidinium ring adopts a chair conformation. In the crystal structure, the cations, anions and solvent molecules are connected by intermolecular O—H...O, N—H...O and C—H...O hydrogen bonds, forming a three-dimensional network.
