ABSTRACT: In the title compound, [Co(C(16)H(8)O(8))(C(12)H(8)N(2))(2)]·2H(2)O, the Co atom located on a twofold rotation axis. It is six-coordinated by two O atoms from one 5,5'-dicarboxy-biphenyl-2,2'-dicarboxyl-ate anion and four N atoms from two 1,10-phenanthroline mol-ecules in a distorted octa-hedral environment. The crystal packing is stabilized by O-H?O hydrogen bonds.

Triaqua-(1,10-phenanthroline-2,9-dicarboxyl-ato)cobalt(II) dihydrate.

Project description:The title compound, [Co(C(14)H(6)N(2)O(4))(H(2)O)(3)]·2H(2)O, has two-fold crystallographic symmetry. The Co(II) atom is in a distorted penta-gonal-bipyramidal coordination environment with two N atoms and two O atoms from a tetradentate 1,10-phenanthroline-2,9-dicarboxyl-ate ligand and one O atom from a water mol-ecule forming the penta-gonal plane, and two O atoms from two water mol-ecules occupying axial positions. In the crystal, adjacent mol-ecules are linked by O-H?O hydrogen bonds, forming a three-dimensional network.

Poly[(μ(3)-biphenyl-3,3'-dicarboxyl-ato)(1,10-phenanthroline)cadmium].

Project description:In the title compound, [Cd(C(14)H(8)O(4))(C(12)H(8)N(2))](n), the Cd(II) ion is seven-coordinated in a distorted penta-gonal-bipyramidal coordination geometry by five O atoms from bridging biphenyl-3,3'-dicarboylate (dpda) ligands and two N atoms from a 1,10-phenanthroline (1,10-phen) ligand. In the crystal, dinuclear units with a Cd⋯Cd separation of 3.8208 (7) Å are observed. Each of these dinuclear units is bridged via 3,3'-bpda in a chelating/chelating and bridging fashion, generating a zigzag chain along the c axis. Neighboring chains are further packed via weak π-π inter-actions between inter-chain parallel 1,10-phen rings [centroid-centroid distance = 3.5197 (9) Å] into a three-dimensional supra-molecular architecture.

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.

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.

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.

Poly[[(μ(3)-5,6-dicarboxy-bicyclo-[2.2.2]oct-7-ene-2,3-dicarboxyl-ato)(1,10-phenanthroline)copper(II)] monohydrate].

Project description:In the title compound, {[Cu(C(12)H(10)O(8))(C(12)H(8)N(2))]·H(2)O}(n), the Cu(II) ion is five-coordinated by two N atoms from one phenanthroline ligand and three O atoms from three different H(2)L(2-) anions (H(4)L is bicyclo-[2.2.2]oct-7-ene-2,3,5,6-tetra-carboxylic acid) in a distorted square-pyramidal geometry. Each H(2)L(2-) ion bridges three Cu(II) atoms to form a zigzag sheet parallel to the ab plane. The crystal structure is consolidated by O-H⋯O hydrogen bonds.

Tetra-aqua-bis(1,10-phenanthroline)bis-[?(2)-1H-pyrazole-3,5-dicarboxyl-ato(3-)]tricopper(II) dihydrate.

Project description:The title compound, [Cu(3)(C(5)HN(2)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, is a trinuclear copper(II) complex in which two centrosymmetrically related pyrazole-3,5-dicarboxyl-ate(3-) and 1,10-phenanthroline ligands bind three Cu(II) atoms, with one Cu(II) atom located on a center of symmetry. In each complex, there are four coordinated water mol-ecules and two solvent water mol-ecules, which participate in extensive hydrogen-bond patterns. These inter-actions, as well as ?-? inter-actions between neighbouring 1,10-phenanthroline ligands [shortest atom-to-atom distance = 3.363?(3)?Å], extend the crystal structure into a three-dimensional supra-molecular network.

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.

Poly[[tetra-aqua-(μ(6)-2,2'-diiodo-biphenyl-4,4',5,5'-tetra-carboxyl-ato)dizinc(II)] dihydrate].

Project description:In the title compound, {[Zn(2)(C(16)H(4)I(2)O(8))(H(2)O)(4)]·2H(2)O}(n), two crystallographically independent Zn(II) atoms are each located on a twofold rotation axis. Both Zn(II) atoms are in distorted octa-hedral coordination geometries: one is coordinated by six O atoms from four carboxyl-ate groups, while the other is coordinated by two carboxyl-ate groups and four water mol-ecules. The tetra-carboxyl-ate ligand mol-ecules connect the Zn(II) atoms, completing a three-dimensional metal-organic framework. O-H⋯O hydrogen bonds link the metal-organic framework with the uncoord-inated water mol-ecules.
