Crystal structure of the 1:2 adduct of bis(piperidinium) sulfate and 1,3-dimethylthiourea

Abstract

In the title compound, 2C5H12N+·SO42−·2C3H8N2S, the C=S groups of the two independent 1,3-dimethylurea molecules and the sulfur atom of the anion lie on twofold axes. The packing is centred on bis(piperidinium) sulfate ribbons parallel to the c axis; the cations are hydrogen bonded to the sulfate by N—H...O and C—H...O interactions. The 1,3-dimethylurea molecules are also hydrogen bonded to sulfate O atoms, and project outwards from the ribbon parallel to the b axis.
