Crystal structure of piperazine-1,4-diium bis(4-aminobenzenesulfonate)
The asymmetric unit of the title salt, C4H12N2 (2+)·2C6H6NO3S(-), consists of half a piperazindiium dication, located about an inversion centre, and a 4-amino-benzene-sulfonate anion. The piperazine ring adopts a chair conformation. In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. Within the framework there are C-H⋯π in...
متن کاملPiperazine-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...
متن کاملCrystal structure of 1,4-bis(3-ammoniopropyl)piperazine-1,4-diium bis[dichromate(VI)]
The asymmetric unit of the organic-inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis-(3-ammonio-prop-yl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4 tetra-hedra of the anion are in an almost eclipsed conformation. In...
متن کاملCrystal structure of the pyridine–diiodine (1/1) adduct
In the title adduct, C5H5N·I2, the N-I distance [2.424 (8) Å] is remarkably shorter than the sum of the van der Waals radii. The line through the I atoms forms an angle of 78.39 (16)° with the normal to the pyridine ring.
متن کاملPiperazine-1,4-diium bis(2,4,5-tricarboxybenzoate) dihydrate
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...
