Piperazine-1,4-diium bis-(2,4,5-tricarb-oxy-benzoate) dihydrate.

ABSTRACT: In the title hydrated salt, C4H12N2 (2+)·2C10H5O8 (-)·2H2O, the piperazinediium cation, lying about an inversion center, adopts a chair conformation. The benzene ring of the anion makes dihedral angles of 25.17?(8)° with the carboxyl-ate group and angles of 8.50?(7), 20.07?(7) and 80.86?(8)° with the three carb-oxy-lic acid groups. In the crystal, the cations, anions and water mol-ecules are connected by O-H?O and N-H?O hydrogen bonds into double layers parallel to (110).

Bis[1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium] bis-(oxonium) cyclo-hexa-phosphate dihydrate.

Project description:In the title compound, 2C12H20N2 (2+)·2H3O(+)·P6O18 (6-)·2H2O, a protonated water mol-ecule bridges the centrosymmetrical anionic P6O18 ring via O-H⋯O hydrogen bonds. The centrosymmetric hydrogen-bonded rings formed by four oxonium cations and four phosphate anions can be described by an R 4 (8)(36) graph-set motif. The ring motifs are connected by hydrogen bonds into inorganic layers perpendicular to [100]. The 1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium cations are located between the layers, compensating their negative charge and establishing N-H⋯O hydrogen bonds with the O atoms of the anionic framework.
