title: 4,4'-(Propane-1,3-di-yl)dipiperidinium sulfate monohydrate.
abstract: In the title compound, C(13)H(28)N(2) (2+)·SO(4) (2-)·H(2)O, extensive hydrogen-bonding inter-actions between the protonated 4,4'-(propane-1,3-di-yl)dipiperidinium ions, the sulfate anions and the water mol-ecules lead to a three-dimensional pillared and layered structure with the 4,4'-(propane-1,3-di-yl)-dipiperidinium ions acting as the pillars.
