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

ABSTRACT: 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.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] pyridine-3,5-dicarboxyl-ate trihydrate].

Project description:The crystal structure of the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(3)NO(4))·3H(2)O}(n), consists of Co(II) polymeric complex cations, uncoordinated pyridine-3,5-dicarboxyl-ate anions and lattice water mol-ecules. The Co(II) cation is coordinated by two N atoms from two 4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The 4,4'-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4'-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O-H⋯O hydrogen bonding network is present in the crystal structure.

μ-4,4'-Bipyridine-κN:N'-bis-[aqua-(4,4'-bi-pyridine-κN)(l-valinato-κN,O)copper(II)] dinitrate dihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(5)H(10)NO(2))(2)(C(10)H(8)N(2))(3)(H(2)O)(2)](NO(3))(2)·2H(2)O, each of the two l-valinate anions chelates a Cu(II) center through the amino N and carboxyl-ate O atom, forming a five-membered ring. A 4,4'-bipyridine mol-ecule bridges two water-coordinated Cu atoms, each of which is connected to another 4,4'-bipyridine, giving rise to a square-pyramidal coordination geometry for the Cu(II) centers. The dinuclear dications, nitrate anions and uncoord-inated water mol-ecules are linked into a two-dimensional structure.

Project description:In the title complex, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(10)H(6)O(6)S(2))}(n), the [Zn(4,4'-bipy)(H(2)O)(4)](2+) (4,4'-bipy is 4,4'-bipyridine) cations are linked into linear chains along [001] by the 4,4'-bipy ligands. The Zn(II) ion exhibits a slightly distorted octa-hedral coordination geometry in which the four water mol-ecules are in the equatorial positions. The anions are hydrogen bonded to the polycationic chains by O-H⋯O hydrogen bonds, forming a three-dimensional network. The Zn(II) ion, 4,4'-bipy ligand and anion lie on special positions of 2/m site symmetry.

catena-Poly[[[aqua-silver(I)]-μ-4,4'-bipyridine-κN:N'] 4-amino-benzoate nitrate hydrate].

Project description:In the structure of the title compound, 2[Ag(C(10)H(8)N(2))(H(2)O)](C(7)H(6)NO(2))(NO(3))·H(2)O, the Ag(I) atom is three-coordinated in a T-shaped configuration by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) ligands at short distances and by one water O atom at a longer distance. Each bipy ligand bridges two neighbouring Ag(I) atoms, forming a chain structure extending parallel to [101]. The complete 4-amino-benzoate anion, the nitrate anion and the uncoordinated water mol-ecule are located on mirror planes: together with the coordinated water mol-ecule, they form N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, stabilizing the crystal structure.

cis-Aqua-bis(2,2'-bipyridine-κN,N')fluoridochromium(III) bis-(perchlorate) dihydrate.

Project description:The title mixed aqua-fluoride complex, [CrF(C(10)H(8)N(2))(2)(H(2)O)](ClO(4))(2)·2H(2)O, has been synthesized by aqua-tion of the corresponding difluoride complex using lanthan-ide(III) ions as F(-) acceptors. The complex crystallizes with a Cr(III) ion at the center of a distorted octa-hedral coordination polyhedron with a cis arrangement of ligands. The crystal packing shows a hydrogen-bonding pattern involving water mol-ecules, the coordinated F atom and the perchlorate anions.

catena-Poly[[(2,2'-bipyrimidine-κN,N)diperchloratocopper(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:The central CuN(4)O(2) motif of the title compound, [Cu(ClO(4))(2)(C(8)H(6)N(4))(C(10)H(8)N(2))](n), exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal centre, showing a considerably long Cu-O bond distance of 2.634 (4) Å towards the second perchlorate group occupying the sixth coordination site, giving a (4+1+1)-type coordination mode. The 4,4'-bipyridine (bipy) ligands are highly twisted with respect to each other, the dihedral angle between the two pyridyl ring planes being 38.9 (2)°. The bipy ligands act as bridging ligands between [Cu(ClO(4))(2)(2,2'-bpym)] (2,2'-bpym is 2,2'-bipyrimidine) units, generating an infinite one-dimensional zigzag chain along [010]. Intra- and intermolecular C-H⋯O hydrogen bonds are present in the crystal structure.

Bis(μ-pyridine-2,5-dicarboxyl-ato)-κN,O:O;κO:N,O-bis-[aqua-(2,2'-bipyridine-κN,N')cobalt(II)] dihydrate.

Project description:In the centrosymmetric title compound, [Co(2)(C(7)H(3)NO(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the two Co(II) cations are bridged by pairs of pyridine-2,5-dicarboxyl-ate anions across an inversion center. Besides two pyridine-2,5-dicarboxyl-ate anions, one bidentate 2,2'-bipyridine and one water mol-ecule coordinate to the Co cation, completing a distorted octa-hedral coordination geometry. Within the dinuclear mol-ecule, π-π stacking occurs between parallel pyridine rings with centroid-centroid distances of 3.802 (2) Å. The crystal structure contains extensive O-H⋯O and weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

catena-Poly[[[tetra-aqua-cadmium(II)]-μ-4,4'-bipyridine] fumarate tetra-hydrate].

Project description:In the crystal structure of the title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(4)H(2)O(4))·4H(2)O, the Cd(II) atom, on an inversion centre, is six-coordinated by four O atoms from four water mol-ecules and two N atoms from 4,4'-bpy mol-ecules in a distorted octa-hedral coordination geometry. Weak C-H⋯O inter-actions between uncoordinated carboxyl-ate O atoms of fumaric acid and water mol-ecules contribute to the crystal packing stability.
