Catena-Poly[[[aqua-(2,2'-bipyridine-?(2)N,N')copper(II)]-?-furan-2,5-di-carboxyl-ato-?(2)O(2):O(5)] dihydrate].

ABSTRACT: In the crystal structure of the title compound, {[Cu(C(6)H(2)O(5))(C(10)H(8)N(2))(H(2)O)]·2H(2)O}(n), an infinite chain parallel to [110] is formed by the linking of Cu(H(2)O)(2,2'-bipyridine) units through a furan-2,5-dicarboxyl-ate bridge. The Cu(II) atom shows a square-pyramidal geometry, with one furan-2,5-dicarboxyl-ate O atom in the apical position. The dihedral angle between the planes of the furan ring and the bipyridine mol-ecule is 83.88?(7)°. O(water)-H?O hydrogen bonds connect adjacent chains, generating a layer motif parallel to (001).

Project description:In the title hydrated coordination polymer, {[Zn(C6H2O5)(C10H8N2)(H2O)]·2H2O} n , an infinite [1-10] chain is formed by the linking of [Zn(C10H8N2)(H2O)](2+) entities by bridging, monodentate furan-2,5-dicarboxyl-ate dianionic linkers. The Zn(2+) coordination geometry is a trigonal bipyramid, with one N atom (from 2,2'-bipyridine) and one O atom (from the bridging dianion) in the axial positions. For each Zn(II) atom, the dihedral angle between the furan ring of its coordinated bridging ligand and its coordinated bipyridine ring system is 87.19?(8)°. O-H?O hydrogen bonds involving both the coordinated and uncoordinated water mol-ecules generate a layer motif parallel to (001).

catena-Poly[[[diaqua-terbium(III)]-μ-6-carboxy-nicotinato-μ-pyridine-2,5-di-carboxyl-ato] dihydrate].

Project description:The title compound, {[Tb(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tm(III) compound [Li, Zhang, Wang & Bai (2009). Acta Cryst. E65, m411]. The Tb(III) atom is octa-coordinated by two water mol-ecules and by four carboxyl-ate O atoms and two pyridyl N atoms from two pyridine-2,5-dicarboxyl-ate (2,5-pydc) and two 6-carboxy-nicotinate (2,5-Hpydc) ligands. The 2,5-pydc and 2,5-Hpydc ligands bridge Tb(III) atoms, generating helical coordination polymers along [001]. An extensive network of O-H⋯O hydrogen bonds is formed between the coordination polymers and the uncoordinated water mol-ecules. The refined Flack parameter of 0.54 (2) suggests inversion twinning.

catena-Poly[[[?-aqua-penta-aqua-dizinc(II)]-?(4)-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H?O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.

Tetra-aqua-(2,2'-bipyridine-5,5'-dicarboxyl-ato-?N,N')nickel(II) dihydrate.

Project description:In the title compound, [Ni(C(12)H(6)N(2)O(4))(H(2)O)(4)]·2H(2)O, obtained from a basic solution of 2,2'-bipyridine-5,5'-dicarboxyl-ate and nickel(II) chloride in water, the central Ni(II) cation (site symmetry 2) is coordinated by two N atoms from the 2,2'-bipyridine-5,5'-dicarboxyl-ate ligand and four aqua O atoms. The N-Ni-N angle is 78.64?(8)°. Weak but significant ?-? stacking inter-actions exist between the pyridine rings with a centroid-centroid distance of 3.652?(8)?Å. In addition, four O atoms of the two carboxyl groups form hydrogen bonds with both coordinated and uncoordinated water mol-ecules, forming an infinite three-dimensional network.

(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(?-pyridine-2,5-dicarboxyl-ato)-?N,O:O;?O:N,O-bis-[aqua-(2,2'-bipyridine-?N,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, ?-? 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?? inter-actions.

Synchrotron study of poly[[di-?-aqua-(?-2,2'-bipyridyl-5,5'-dicarboxyl-ato)di-potassium] dihydrate].

Project description:The title compound, {[K(2)(C(12)H(6)N(2)O(4))(H(2)O)(2)]·2H(2)O}(n), forms a three-dimensional coordination polymer in the solid state. The asymmetric unit consists of one K(+) ion, half of a 2,2'-bipyridyl-5,5'-dicarboxyl-ate ligand, one coordinated water mol-ecule and one solvent water mol-ecule. The K(+) ion is 7-coordinated by the oxygen atoms of two water mol-ecules and by five oxygen atoms of four carboxyl-ate groups, one of which is chelating. The extended structure can be described as a binodal network in which each K(+) is a six-connected node, bonding to four carboxyl-ate groups and two bridging water mol-ecules, and the 2,2'-bipyridyl-5,5'-dicarboxyl-ate linkers are eight-connected nodes, with each carboxyl-ate group bridging four metal centers. Overall, this arrangement generates a complex network with point symbol {3(4).4(12).5(12)}{3(4).4(4).5(4).6(3)}(2). Both of the bridging water mol-ecules participate as donors in hydrogen-bonding inter-actions; one to solvent water mol-ecules and a second to an oxygen atom of a carboxyl-ate group.

Aqua-(2,2'-bipyridine)trifluorido-chromium(III) dihydrate.

Project description:The title compound, [CrF(3)(C(10)H(8)N(2))(H(2)O)]·2H(2)O, was prepared by the reaction of CrF(3) and 2,2'-bipyridine under hydrous conditions. The metal centre is coordinated in a distorted octahedral mode by two N atoms from the organic ligand, three F atoms and one O atom of a water molecule. . The crystal packing is stabilized by O-H?O and O-H?F hydrogen-bonding contacts, which form a one-dimensional belt extending parallel to (100).

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.
