title: 1-Phenyl-piperazine-1,4-diium bis-(hydrogen sulfate).
abstract: In the title compound, C(10)H(16)N(2) (2+)·2HSO(4) (-), the S atoms adopt slightly distorted tetra-hedral geometry and the diprotonated piperazine ring adopts a chair conformation. In the crystal, the 1-phenyl-piperazine-1,4-diium cations are anchored between chains formed by the sulfate entities via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds. These hydrogen bonds contribute to the cohesion and stability of the network of the crystal structure.
