Piperazine-1,4-diium diacetate
In the title salt, C(4)H(12)N(2) (2+)·2C(2)H(3)O(2) (-), the piperazine-1,4-diium cation has 2/m symmetry with the NH(2) unit located on a mirror plane and the acetate anion has m symmetry with all non-H atoms and one H atom located on a mirror plane. The piperazine ring adopts a chair conformation. In the crystal, the cations are linked with the anions via N-H⋯O hydrogen bonding into chains pa...

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 co...
متن کاملPiperazine-1,4-diium bis(3,5-dicarboxybenzoate)
The asymmetric unit of the title salt, C(4)H(12)N(2) (2+)·2C(9)H(5)O(6) (-), comprises one half of the piperazine-1,4-diium dication lying on an inversion centre and one 3,5-dicarboxy-benzoate anion. In the crystal, the ions are linked into a two-dimensional framework parallel to (101) by N-H⋯O and O-H⋯O hydrogen bonds.
متن کاملPiperazine-1,4-diium bis(perchlorate) dihydrate
The asymmetric unit of the title compound, C(4)H(12)N(2) (2+)·2ClO(4) (-)·2H(2)O, contains half of a piperazinediium cation, one perchlorate anion and one water mol-ecule. The diprotonated piperazine ring, which is completed by crystallographic inversion symmetry, adopts a chair conformation. In the crystal structure, the cations and anions are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen...
متن کاملPiperazine-1,4-diium bis[tetrachloridoaurate(III)] dihydrate
In the title compound, (C(4)H(12)N(2))[AuCl(4)](2)·2H(2)O, the Au(III) atom has a square-planar geometry. The piperazinium dication lies on an inversion centre and adopts a typical chair conformation. In the crystal, a combination of N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds results in the formation of a three-dimensional network.
