Aqua-bis(2,2'-bipyridine-?N,N')(1H-indole-2-carboxyl-ato-?O)nickel(II) 1H-indole-2-carboxyl-ate dihydrate.

ABSTRACT: The hydro-thermal reaction of Ni(2)(OH)(2)CO(3) with 2,2'-bipyridine and 2-indolyl-formic acid in CH(3)OH/H(2)O at 423?K for 7?d produced the novel Ni(II) complex [Ni(C(9)H(6)NO(2))(C(10)H(8)N(2))(2)(H(2)O)](C(9)H(6)NO(2))·2H(2)O. The asymmetric unit of the title compound consists of a monovalent [Ni(L)(bpy)(2)(H(2)O)](+) cation (bpy is 2,2'-bipyridine and L is 1H-indole-2-carboxyl-ate), an L anion and two solvent water mol-ecules. In the [Ni(L)(bpy)(2)(H(2)O)](+) cations, the Ni atom coordinates to four N atoms from the two bpy ligands and two O atoms, one from a L anion and the other from a water mol-ecule to complete an significantly distorted NiN(4)O(2) octa-hedron. The coordinated and solvate water mol-ecules form an extensive series of O-H?O hydrogen bonds. N-H?O and C-H?O hydrogen bonds are also present and the mol-ecules are inter-linked, forming a three-dimensional network.

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.

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 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°).

Project description: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).

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.

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.

Poly[[tetra-aqua-(?(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.

Diaqua-(2,2'-bipyridine-6,6'-dicarboxyl-ato)nickel(II).

Project description:In the title compound, [Ni(C(12)H(6)N(2)O(4))(H(2)O)(2)], the Ni(II) atom (site symmetry 2) displays a distorted cis-NiN(2)O(4) octa-hedral coordination geometry with two N atoms and two O atoms of the tetra-dentate 2,2'-bipyridine-6,6'-dicarboxyl-ate ligand in the equatorial plane and two water mol-ecules in axial positions. The complete dianionic ligand is generated by crystallographic twofold symmetry. In the crystal, a two-dimensional supra-molecular structure parallel to (001) is formed through O-H?O hydrogen-bond inter-actions between the coordinated water mol-ecules and the O atoms of nearby carboxyl-ate groups.

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.
