1-Phenylpiperazine-1,4-diium bis(hydrogen sulfate)

Abstract

In the title compound, C10H16N22+·2HSO4-, 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.
