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.
