4,4'-(2,6-Dihydroxy-naphthalene-1,5-diyldimethyl-ene)dipyridinium bis-(per-chlorate).

ABSTRACT: The title compound, C(22)H(20)N(2)O(2) (2+)·2ClO(4) (-), was synthesized by the reaction of naphthalene-2,6-diol with pyridine-4-carbaldehyde, 4-picolylamine and perchloric acid. There is a centre of symmetry at the mid-point of the central C-C bond of the cation. The two pyridine rings are parallel to each other, and the dihedral angle between the naphthalene ring system and the pyridine ring is 80.68?(11)°. All the bond lengths and angles are normal. Classical inter-molecular O-H?O and N-H?O hydrogen bonds connect cations and anions, forming a one-dimensional chain structure.

4,4'-(o-Phenyl-enedioxy-dimethyl-ene)dipyridinium dinitrate.

Project description:The cation of the salt, C(18)H(18)N(2)O(2) (2+)·2NO(3) (-), lies about a twofold rotation axis.

The NH(3) (+) functional groups are also involved in N-H?O hydrogen bonds with the water mol-ecules, forming an infinite three-dimensional framework in the crystal structure.

Crystal structure of 4,4'-bipyridine-1,1'-diium naphthalene-2,6-di-sulfonate dihydrate.

Project description: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 bond of the naphthalene group of the anion. In the crystal, the anions and cations stack alternately along the a axis with ?-? inter-actions [inter-centroid distance = 3.491?(1)?Å]. The anions are linked via O-H?O(sulfonate) hydrogen bonds involving two inversion-related water mol-ecules, forming chains along [10-1]. These chains are bridged by bifurcated N-H?(O,O) hydrogen bonds, forming a three-dimensional framework structure. There are also C-H?O hydrogen bonds present, reinforcing the framework structure.
