چکیده
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, inter-molecular N-H⋯O hydrogen-bonding inter-actions between tetra-bromo-terephthalate dianions and protonated 4,4'-bipyridinium dications result in the formation of a chain-like structure. Further O-H⋯O hydrogen bonds between carboxyl-ate O atoms and water mol-ecules lead to the formation of a two-dimensional network in the crystal structure.

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...

The reaction of 2-hy-droxy-1,4-naphtho-quinone and 4,4'-bipyridine with zinc acetate produced the title compound, [Zn(C(10)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)]·C(10)H(8)N(2)·2H(2)O. The bond lengths and angles around the metal atom indicate a deviation from octa-hedral geometry. The two naphtho-quinone ligands coordinate in a cis fashion, with the 4,4'-bipyridine ligand and the water mol-ecules ...
