Abstract

The title compound, C17H19Cl2N2OS+·Cl−, was synthesized from 2-acetothio­phene, 1-(2,3-dichloro­phen­yl)piperazine and paraformaldehyde. In the cation, the thienyl ring is coplanar with the oxopropyl group. The protonated piperazine ring exhibits a chair conformation. In the crystal packing the cations are connected by C—H⋯O and C—H⋯Cl hydrogen bonds.
