4,4'-Bipyridinium bis(perchlorate)-4-aminobenzoic acid-4,4'-bipyridine-water (1/4/2/2).

ABSTRACT: In the structure of the title compound, C(10)H(10)N(2) (2+)·2ClO(4) (-)·4C(7)H(7)NO(2)·2C(10)H(8)N(2)·2H(2)O, the 4,4'-bipyridinium cation has a crystallographically imposed centre of symmetry. The cation is linked by N-H?N hydrogen bonds to adjacent 4,4'-bipyridine mol-ecules, which in turn inter-act via O-H?N hydrogen bonds with 4-amino-benzoic acid mol-ecules, forming chains running parallel to [30]. The chains are further connected into a three-dimensional network by N-H?O and O-H?O hydrogen-bonding inter-actions involving the perchlorate anion, the water mol-ecules and the 4-amino-benzoic acid mol-ecules. In addition, ?-? stacking inter-actions with centroid-centroid distances ranging from 3.663?(6) to 3.695?(6)?Å are present. The O atoms of the perchlorate anion are disordered over two sets of positions, with refined site occupancies of 0.724?(9) and 0.276?(9).

Bis(4,4'-bipyridinium) dodeca-tungsto-silicate 4,4'-bipyridine hexa-hydrate.

Project description:The title compound, (C(10)H(10)N(2))(2)[SiW(12)O(40)]·C(10)H(8)N(2)·6H(2)O or (4,4'-bipyH(2))(2)[SiW(12)O(40)].(4,4'-bipy)·6H(2)O (4,4'-bipy is 4,4'-bipyridine), was prepared under hydro-thermal conditions. The asymmetric unit contains a discrete Keggin-type [SiW(12)O(40)](4-) anion (located on a twofold axis), one 4,4'-bipy (located on a twofold axis), two (4,4'-bipyH(2))(2+) cations and six uncoordinated water mol-ecules. The polyoxoanion is constructed from a central SiO(4) tetra-hedron which shares its O atoms with four trinuclear W(3)O(13) groups, each of which is made up of three edge-sharing WO(6) octa-hedra. The water mol-ecules and [SiW(12)O(40)](4-) anions are linked through hydrogen bonds.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] bis-(perchlorate) 4,4'-bipyridine disolvate dihydrate].

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.

Poly[[bis-(?-4,4'-bipyridine-?(2)N:N')copper(I)] perchlorate 0.24-hydrate].

Project description:The title copper(I) polymeric compound, {[Cu(C(10)H(8)N(2))(2)]ClO(4)·0.24H(2)O}(n), obtained by the reaction of Cu(ClO(4))(2) and 4,4'-bipyridine (4,4'-bpy) under hydro-thermal conditions, features a fourfold-inter-penetrated diamondoid coordination framework. The asymmetric unit consists of two Cu(I) atoms, three 4,4'-bpy ligands in general positions and two halves of two centrosymmetric 4,4'-bpy ligands, two ClO(4) (-) anions and water mol-ecule with a site-occupancy factor of 0.480?(17). The Cu(I) atoms are in a distorted tetra-hedral coordination environment and are bridged by 4,4'-bpy ligands, forming a diamondoid cationic polymeric framework that encloses two symmetry-independent channels along [100], which accommodate perchlorate anions and water mol-ecules.

1,1'-Dimethyl-4,4'-bipyridinium bis-(triiodide).

Project description:In the title compound, C(12)H(14)N(2) (2+)·2I(3) (-), the 1,1'-dimethyl-4,4'-bipyridinium (DMBP) dication is charge balanced by two triiodide ions. The DMBP dication is planar within 0.010 (5) Å. The asymmetric unit contains only half of the dication, the other half being generated by an inversion center. Weak C-H⋯I inter-actions link the ions into sheets parallel to (121).

catena-Poly[4,4'-bipyridinium [[diaqua-disulfatocadmium(II)]-?-4,4'-bipyridine-?N:N'] dihydrate].

Project description:The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the non-coordinated bipyridinium counterion. O-H?O and N-H?O hydrogen bonding inter-actions and ?-? stacking inter-actions in the structure are responsible for the supra-molecular assembly.

4,4'-Bipyridinium bis-(2-carboxy-pyridine-3-carboxyl-ate).

Project description:The title salt, C(10)H(10)N(2) (2+)·2C(7)H(4)NO(4) (-) or (4,4'-bpyH(2))(py-2,3-dcH)(2), prepared by the reaction between pyridine-2,3-dicarboxylic acid (py-2,3-dcH(2)) and 4,4'-bipyridine (4,4'-bpy), consists of two anions and one centrosymmetric dication.

These inter-actions, along with other O-H?O and C-H?O hydrogen bonds, ?-? stacking [centroid-centroid distances 3.621?(7) and 3.612?(7)?Å] and ion pairing, lead to the formation of the three-dimensional structure.

Bis[4-(4-pyridyl)pyridinium] ?-4,4'-bipyridine-bis-[tetra-aqua-(4,4'-bipyridine)manganese(II)] bis-(5-sulfonatobenzene-1,3-dicarboxyl-ate) 4,4'-bipyridine solvate penta-deca-hydrate.

Project description:The crystal structure of the title compound, (C(10)H(9)N(2))(2)[Mn(2)(C(10)H(8)N(2))(3)(H(2)O)(8)](C(8)H(3)O(7)S)(2)·C(10)H(8)N(2)·15H(2)O, consists of dinuclear Mn(II) complex cations, sulfonato-benzene-dicarboxyl-ate trianions, 4-(4-pyridyl)pyridinium cations, uncoordin-ated 4,4'-bipyridine and uncoordinated water mol-ecules. One 4,4'-bipyridine mol-ecule bridges two Mn atoms, forming a centrosymmetric dinuclear complex; the mid-point of the C-C bond linking the pyridine rings of the bridging ligand is located on an inversion center. Each Mn(II) atom is coordinated by four water and two 4,4'-bipyridine mol-ecules in a distorted octa-hedral geometry. The Mn(II) atom deviates by 0.591?(5) and 0.209?(2)?Å from the mean planes of the coordinated pyridine rings. In the 4-(4-pyridyl)pyridinium cation, the two pyridine rings are twisted with respect to each other, making dihedral angle of 34.78?(17)°. The uncoordinated bipyridine mol-ecule is also centrosymmetric. One of uncoordinated water mol-ecules has site symmetry 2, and the other uncoordinated water mol-ecule is located close to an inversion center and its one H atom is disordered equally over two sites. Extensive ?-? stacking between pyridine rings is observed and an extensive hydrogen-bonding network of the types N-H?N, O-H?N and O-H?O is present.
