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

ABSTRACT: 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.

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.

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.

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.

catena-Poly[[[bis-(4-methyl-benzoato-?O,O')zinc(II)]-?-4,4'-bipyridine-?N:N'] tetra-hydrate].

Project description:The asymmetric unit of the title compound, {[Zn(C(7)H(7)O(2))(2)(C(10)H(8)N(2))]·4H(2)O}(n), contains a highly distorted octa-hedral Zn(II) metal center strongly coordinated by two N atoms of two 4,4'-bipyridine (4,4'-bipy) ligands and chelated by two 4-methyl-benzoate anions. The crystallographic inversion center and glide plane present at the center of the C-C single bond of 4,4'-bipy, along with the cis coordination motif of the 4,4'-bipy, lead to one-dimensional zigzag chains. There are a large number of water mol-ecules in the crystal structure, which also form one-dimensional chains through O-H?O hydrogen bonds.

Poly[[bis-(?(2)-4,4'-bipyridine)[?(2)-(2,4-dichloro-phen-oxy)acetato]copper(I)] nitrate].

Project description:The title compound, {[Cu(2)(C(8)H(5)Cl(2)O(3))(C(10)H(8)N(2))(2)]NO(3)}(n) was prepared by reacting copper(II) nitrate with 4,4'-bipyridine (4,4'-bipy) and (2,4-dichloro-phen-oxy)acetic acid under solvothermal conditions. Each of two copper(I) atoms in the asymmetric unit is three-coordinated by two N atoms from two 4,4'-bipy ligands and one O atom from the (2,4-dichloro-phen-oxy)acetate ligand. As both ligands act as bridging ligands, a double-stranded chain structure is observed.

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

Project description: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).

Poly[bis-(?(2)-4,4'-bipyridine)bis-(3-nitro-benzoato)cobalt(II)].

Project description:The hydro-thermal reaction of cobalt nitrate with 4,4'-bipyridine and 3-nitro-benzoic acid lead to the formation of the title complex, [Co(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n). In the crystal structure, the Co(II) atoms are coordinated by two terminal carboxyl-ate anions and four 4,4'-bipyridine ligands within slightly distorted octa-hedra. The Co(II) atom and one of the two independent 4,4'-bipyridine ligands are located on a twofold rotation axis, while the second independent 4,4'-bipyridine mol-ecule is located on a centre of inversion. One of the two rings of one 4,4'-bipyridine ligand is disordered over two orientations and was refined using a split model [occupancy ratio 0.68?(2):0.32?(2)]. The Co(II) atoms are connected by the 4,4'-bipyridine ligands into layers, which are located parallel to the ab plane.
