Poly[bis(2,2'-bipyridine-?N,N')heptadeca-?-oxido-tetraoxidodicopper(II)divanadate(IV)hexavanadate(V)].

ABSTRACT: In the title complex, [Cu(2)V(8)O(21)(2,2'-bpy)(2)](n) (bpy = bipyridine, C(10)H(8)N(2)), the asymmetric unit contains four independent V atoms briged by 11 O atoms, one of which lies on an inversion center, and a [Cu(2,2'-bpy)](2+) unit. Three V atoms in the polyoxoanion exhibit distorted tetra-hedral coordination geometries while the fourth V atom adopts a trigonal-bipyramidal geometry. The Cu atom adopts a square-pyramidal geometry being coordinated by two nitro-gen donors of a 2,2'-bpy ligand, and three bridging O atoms which are linked with V atoms. The V(8) polyoxoanion is connected to [Cu(2,2'-bpy)](2+) cations, resulting in a two-dimensional layer structure extending parallel to (010). C-H?O hydrogen bonding consolidates the structure.

Poly[bis-(2,2'-bipyridine-?N,N')deca-?-oxido-dioxidodicopper(II)tetra-vanadium(V)].

Project description:The title compound, [Cu(2)V(4)O(12)(C(10)H(8)N(2))(2)](n), shows a two-dimensional copper-vanadate layer composed of eight-membered rings, each containing four corner-sharing VO(4) tetra-hedra; these are linked through six penta-coordinated Cu(II) atoms with the 2,2'-bipyridine ligands attached and pointing above and below the plane of the layer. The Cu atom is coordinated by two N donors from the 2,2'-bipyridine ligand and three O atoms from three adjacent VO(4) units to form a distorted tetragonal pyramid. These layers are further connected by ?-? inter-actions between inter-leaving bipyridine ligands of adjacent layers [centroid-centroid distances = 3.63?(1) and 3.68?(1)?Å] into a three-dimensional supra-molecular structure.

(?-Oxalato-?O,O:O,O)bis-[bis-(2,2'-bipyridine-?N,N')cobalt(II)] ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxido-hexa-tungstate(VI).

Project description:The asymmetric unit of the title compound, [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)][W(6)O(19)], consists of one half of the complex [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)](2+) cation and one half of the Lindqvist-type [W(6)O(19)](2-) isopolyanion. Both constituents are completed by crystallographic inversion symmetry. In the dimeric cation, the Co(II) atom is surrounded in a distorted octa-hedral coordination by four N atoms from two chelating 2,2'-bipyridine ligands and by two O atoms from the chelating oxalate anion. The Lindqvist-type anion exhibits the characteristic W-O bond-length distribution, with the shortest bonds being the W-O(terminal) bonds and the longest being those to the central O atom.

Bis(?-2,2'-disulfanediyldibenzoato)bis-[aqua-(2,2'-bipyridine)-nickel(II)].

Project description:In the centrosymmetric title complex, [Ni(2)(C(14)H(8)O(4)S(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Ni(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand, three carboxyl-ate O atoms (one bidentate and one monodentate) from two different disulfanediyldibenzoate ligands and one O atom from a coordinated water mol-ecule in an octa-hedral coordination geometry. The disulfanediyldibenzo-ate dianion bridges two Ni(II )atoms. Adjacent mol-ecules are linked through the coordinated water mol-ecules, forming a O-H?O hydrogen-bonded chain running along the a axis.

Bis(?-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu?Cu separation of 6.136?(16)?Å. The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43?Å) Cu?O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Bis(?-biphenyl-2,2'-dicarboxyl-ato)bis-[aqua-(2,2'-bipyridine)cadmium(II)].

Project description:In the centrosymmetric dinuclear mol-ecule of the title compound, [Cd(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Cd(2+) ion is coordinated by three O atoms from two different diphenyl-dicarboxyl-ate (dpa) ligands (one O,O'-bidentate and one monodentate), a chelating bipyridine ligand and a water mol-ecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN(2)O(4) coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intra-molecular O-H?O hydrogen bonds.

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], was obtained by solvothermal synthesis. The Cu(II) atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxyl-ate ligands, leading to a distorted octahedral environment. Each carboxyl-ate group makes one short Cu-O bond [1.9608 (14) and 1.9701 (14) Å] and one longer Cu-O contact [2.4338 (17) and 2.5541 (17) Å] to each Cu(II) atom. The biphenyl-2,2'-dicarboxyl-ate ligands bridge between Cu(II) atoms, forming a dinuclear complex around a crystallographic inversion centre.

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)cobalt(II)].

Project description:In the title compound, [Co(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], the Co(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand and two O atoms from two biphenyl-2,2'-dicarboxyl-ate (2,2'-dpa) ligands in a distorted planar geometry. Longer Co-O contacts [2.437 (3) and 2.552 (3) Å] are formed to the second O atom of each coordinated carboxyl-ate group so that these groups approximate a bidentate coordination mode and the coordination geometry around Co(II) approaches distorted octa-hedral. The 2,2'-dpa ligands bridge two Co(II) atoms, forming a cyclic dinuclear complex around a centre of inversion.

Bis(2,2'-bipyridine)(5,5'-imino-ditetra-zolato)cadmium(II) 2,2'-bipyridine hemisolvate monohydrate.

Project description:The title complex, [Cd(C(2)HN(9))(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·H(2)O, was prepared under hydro-thermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent mol-ecule and a solvent water mol-ecule. The Cd(II) ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA(-) anion ligand [where H(2)BTA is N,N-bis-(1H-tetra-zol-5-yl)amine], forming an octa-hedral geometry. The complex is linked into a three-dimensional network by O-H⋯N and N-H⋯N hydrogen bonds and by the stacking inter-actions of rings, with distances of 3.5-3.7 Å between the atoms of two parallel 2,2'-bipyridine rings.

Poly[diaqua-bis(2,2'-bipyridine)tris-(μ(4)-2,2'-bipyridine-4,4'-dicarboxyl-ato)dineodymium(III)].

Project description:In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl-ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2'-bipyridine-4,4'-dicarboxyl-ate linkers, resulting in a layered coordination network.
