Piperazine-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...
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.
متن کامل1,4-Bis(carboxymethyl)piperazine-1,4-diium bis(dihydrogen phosphate) dihydrate
In the title salt, C(8)H(16)N(2)O(4) (2+)·2H(2)PO(4) (-)·2H(2)O, the piperazine ring is located around an inversion center and adopts a chair conformation. The dihydrogen phosphate anions and free water mol-ecules are linked via O-H⋯O hydrogen bonds into two-dimensional hydrogen-bonding layers, which are further connected through O-H⋯O and N-H⋯O hydrogen bonds involving the protonated piperazin...
متن کامل3,3′-(Piperazine-1,4-diium-1,4-diyl)dipropionate dihydrate
During the recrystallization of 3-[4-(2-carb-oxy-eth-yl)piperazin-1-yl]propionic acid, the carb-oxy-lic acid H atoms were transferred to the piperazine N atoms, forming the title compound, C(10)H(18)N(2)O(4)·2H(2)O, in which the zwitterion lies about an inversion center. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds connect the zwitterions into a two-dimensional framework parallel to (-10...
