Bis(?-2-phenyl-quinoline-4-carboxyl-ato)-?O,O':O;?O:O,O'-bis-[(2,2'-bipyridine-?N,N')(2-phenyl-quinoline-4-carboxyl-ato-?O,O')cadmium(II)].

ABSTRACT: The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (?-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monodentate, two bidentate. Weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.712?(3)?Å] help to establish the packing of the structure.

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(2,2'-bipyridine-?N,N')bis-(1H-indole-2-carboxyl-ato-?O,O')cadmium-2,2'-bipyridine-water (1/0.5/2).

Project description:The asymmetric unit of title compound, [Cd(C(9)H(6)NO(2))(2)(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·2H(2)O, consists of one complex mol-ecule, one half of an uncoordinated 2,2'-bipyridine mol-ecule and two solvent water mol-ecules. The uncoordinated 2,2'-bipyridine mol-ecule is located on a center of symmetry. Within the complex mol-ecule, the Cd(II) atom is coordinated by four N atoms from two 2,2'-bipyridine ligands and three O atoms from two 1H-indole-2-carboxyl-ate anion ligands, completing a distorted CdN(4)O(3) penta-gonal bipyra-mid. The mol-ecules are assembled into one-dimensional chains along the [100] direction through classical hydrogen bonds (O-H?N, N-H?O and O-H?O). The resulting chains are further connected into two-dimensional supra-molecular layers parallel to the (110) direction by inter-molecular classical hydrogen bonds (N-H?O and O-H?O) from adjacent chains. A three-dimensional supra-molecular network is formed via interlayer and O-H?O hydrogen bonds.

(2,2'-Bipyridine)bis-(3-carboxy-pyrazine-2-carboxyl-ato)copper(II) dihydrate.

Project description:The title six-coordinated distorted octa-hedral complex, [Cu(C(6)H(3)N(2)O(4))(2)(C(10)H(8)N(2))]·2H(2)O, consists of two 3-carboxy-pyrazine-2-carboxyl-ate anions and one 2,2'-bipyridine ligand. There is a twofold rotation axis positioned at the Cu(II) center. The N atoms of the pyrazine ring occupy the axial positions and two proton-transferred O atoms of tbe acid together with the two N atoms of the 2,2'-bipyridine ligand complete the equatorial plane. The inter-actions existing in the crystal structure are inter-molecular O-H⋯O hydrogen bonds, and C-H⋯O and C-O⋯π inter-actions (O⋯π =3.145 Å, C-O⋯π = 149.75°).

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.

Aqua-(2,2'-bipyridine-?N,N')bis-(thio-phene-2-carboxyl-ato-?O)copper(II).

Project description:In the title complex, [Cu(C(5)H(3)O(2)S)(2)(C(10)H(8)N(2))(H(2)O)], the Cu(II) atom is in a distorted square-pyramidal environment, with an Addison ? parameter of 0.07. The coordination geometry is defined by two nitro-gen donors from the 2,2'-bipyridine ligand, two O atoms from two monodentate thio-phene-2-carboxyl-ate ligands and one O atom from the aqua ligand. The latter occupies the elongated apical position. This is different from the related structure of aqua-(1,10-phenanthroline)bis-(thio-phene-2-carboxyl-ato)copper(II) where a carboxyl-ate O atom is in the apical position [Feng et al. (2005 ?). Z. Kristallogr. New Cryst. Struct.220, 429-430]. The uncoordinated carboxyl-ate O atoms form intra- and inter-molecular hydrogen bonds to the aqua ligand. Two neighbouring 2,2'-bipyridine ligands form a ?-stack, with a centroid-centroid distance of 3.683?(2)?Å.

Bis(?-2-phenyl-quinoline-4-carboxyl-ato)bis-[aqua-(1,10-phenanthroline)(2-phenyl-quinoline-4-carboxyl-ato)manganese(II)] dihydrate.

Project description:In the centrosymmetric dinuclear title complex, [Mn(2)(C(16)H(10)NO(2))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the Mn(II) cation is in a distorted octa-hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl-quinoline-4-carboxyl-ate anions. A pair of 2-phenyl-quinoline-4-carboxyl-ate anions bridge two Mn cations, forming the dinuclear mol-ecule. An intra-moleculr O-H?O hydrogen bond occurs. Inter-molecular O-H?O and O-H?N hydrogen bonds are present in the crystal structure.

Poly[[bis-(2,2-bipyridine)-bis-[?(6)-5-(carboxyl-atometh-oxy)benzene-1,3-dicarboxyl-ato]trimanganese(II)] monohydrate].

Project description:The title compound, {[Mn(3)(C(10)H(5)O(7))(2)(C(10)H(8)N(2))(2)]·H(2)O}(n), was synthesized under hydro-thermal conditions. Six carboxyl-ate groups of six 5-(carboxyl-atometh-oxy)benzene-1,3-dicarboxyl-ate anions (OABDC(3-)) join three Mn(II) ions into a trinuclear centrosymmetric [Mn(3)(?(2)-COO)(6)] unit with one Mn site situated on a centre of inversion. The latter Mn(II) ion exhibits a distorted MnO(6) coordination, whereas the other Mn(II) ion has a trigonal-bipyramidal MnN(2)O(3) coordination environment resulting from three carboxylate O atoms and the two N atoms of the bipyridine ligand. Adjacent units are linked to each other by OABDC(3-) ligands into a layer parallel to (010). Within the layer, O-H?O hydrogen-bonding inter-actions involving the uncoordinated and half-occupied water mol-ecule and the free carboxyl-ate O atoms are observed. The layers stack along [010], constructing a three-dimensional structure through ?-? inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.473?(5)?Å.

Bis(2,2'-bipyridine-?N,N')dibromido-cadmium(II).

Project description:In the title complex mol-ecule, [CdBr(2)(C(10)H(8)N(2))(2)], the Cd(II) ion is six-coordinated by two cis-arranged bromide anions and four N atoms of two bidentate 2,2'-bipyridine ligands in a distorted octa-hedral geometry. The dihedral angle formed by the mean planes through the bipyridine ligands is 87.01?(11)°. In the crystal packing, ?-? stacking inter-actions [centroid-centroid distances = 3.837?(6) and 3.867?(11)?Å] link adjacent complex mol-ecules into chains running parallel to the b axis. The chains are further connected by inter-molecular C-H?Br hydrogen bonds into a three-dimensional network.

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.

Bis(quinoline-2-carboxyl-ato-?N,O)lead(II).

Project description:The Pb(II) atom in the title compound, [Pb(C(10)H(6)NO(2))(2)], is N,O-chelated by two quinoline-2-carboxyl-ate anions in a distorted ?-trigonal-bipyramidal environment; four atoms are connected to the Pb(II) atom by regular coordination bonds. The structure also features two somewhat long Pb?O inter-actions [2.952?(3) and 3.014?(3)?Å]. These long inter-actions give rise to a layer coordination polymer having the lead atom in a distorted ?-monocapped octa-hedral geometry.
