Abstract

The asymmetric unit of the title salt solvate, 2C(11)H(15)ClNO(+)·2C(6)H(2)N(3)O(7) (-)·C(2)H(6)OS, contains two crystallographically independent 4-(4-chloro-phen-yl)-4-hydroxy-piperidinium cations, two picrate anions and a dimethyl sulfoxide solvent mol-ecule. In each cation, the piperidinium ring adopts a chair conformation. In the crystal structure, the cations, anions and solvent mol-ecules are connected by inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.
