title: 4-(Methyl-sulfon-yl)piperazin-1-ium chloride.
abstract: In the title mol-ecular salt, C(5)H(13)N(2)O(2)S(+)·Cl(-), the complete cation is generated by crystallographic mirror symmetry, with both N atoms, the S atom and one C atom lying on the reflecting plane. The chloride ion also lies on the mirror plane. The piperazinium ring adopts a chair conformation and the N-S bond adopts an equatorial orientation. In the crystal structure, the component ions are linked into a three-dimensional framework by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds.
