4,4′-Bipyridine-1,1′-diium 2,3,5,6-tetrabromoterephthalate dihydrate
The title compound, C(10)H(10)N(2) (2+)·C(8)Br(4)O(4) (2-)·2H(2)O, consists of a tetra-bromo-terephthalate dianion, a 4,4'-bipyridinium dication and two solvent water mol-ecules. Crystallographic inversion centers are situated at the center of the aromatic ring of the dianion as well as at the midpoint of the carbon-carbon bond connecting the pyridine rings in the dication. In the crystal, inte...

The title hydrated mol-ecular organic salt, C10H10N2 (2+)·C10H6O6S2 (2-)·2H2O, crystallized with half a bipyridinium cation, half a naphthalene-2,6-di-sulfonate anion and a water mol-ecule in the asymmetric unit. The whole cation and anion are generated by inversion symmetry, the inversion centers being at the center of the bridging C-C bond of the cation, and at the center of the fused C-C bon...

In the title mol-ecular salt, C(10)H(10)N(2) (2+)·2Br(-), the dihedral angle between the aromatic rings is 20.83 (14)° and the N-H groups have a transoid conformaton [N-C-C-N = 158.5 (3)°]. In the crystal, the cations are linked to the anions by two N-H⋯Br and five C-H⋯Br hydrogen bonds, generating corrugated sheets incorporating R(2) (1)(7), R(4) (2)(10), R(4) (2)(11) and two different R(4) (2...
متن کامل1,4-Dimethylpiperazine-1,4-diium dibromide dihydrate
In the title hydrated mol-ecular salt, C(6)H(16)N(2) (2+)·2Br(-)·2H(2)O, the complete 1,4-dimethyl-piperazine-1,4-diium dication is generated by crystallographic inversion symmetry and both exocyclic C-N bonds are in equatorial orientations. In the crystal, the components are linked by N-H⋯O and O-H⋯Br hydrogen bonds, generating chains propagating in [110].

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...
