Bis(2,2'-bipyridine-κN,N')bis-[3-(3-hy-droxyphenyl)propenoato-κO,O]cadmium.

ABSTRACT: The title compound, [Cd(C(9)H(7)O(3))(2)(C(10)H(8)N(2))(2)], was synthesized under mild hydro-thermal conditions. The structure of the complex mol-ecule consists of four approximately planar fragments: two 3-(3-hy-droxyphenyl)propenoate residues and two 2,2'-bipyridine ligands [largest deviation from the least-squares planes is 0.240 (1) Å for one of 3-(3-hy-droxy-phenyl)propenoate residues]. The dihedral angles formed by the least-squares planes of the 2,2'-bipyridine ligands and the opposite 3-(3-hy-droxyphenyl)propenoate residues are 22.68 (7) and 26.47 (6)°. The CdN(4)O(4) coordination polyhedron can be described as distorted dodecahedral. Inter-molecular O-H⋯O hydrogen bonds between carboxyl-ate O atoms and hy-droxy groups lead to the formation of chains along the a-axis direction.

Bis(2,2'-bipyridine-κN,N')bis-(1H-indole-2-carboxyl-ato-κO,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.

Bis(2,2'-bipyridine-κN,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, π-π 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(4-amino-benzoato)-κO,O';κO-(2,2'-bipyridine-κN,N')zinc.

Project description:In the title complex, [Zn(C(7)H(6)NO(2))(2)(C(10)H(8)N(2))], the Zn(II) cation is coordinated by two amino-benzoate anions and one 2,2'-bipyridine ligand in a distorted trigonal-bipyramidal geometry. The carboxyl-ate group of one aminobenzoate anion coordinates to the Zn(II) cation in a monodentate manner, whereas the carboxyl-ate group of the other amino-benzoate anion chelates the Zn cation with different Zn-O bond lengths. Inter-molecular N-H⋯N and N-H⋯O hydrogen bonding is present in the crystal structure.

Project description:In the title compound, [Cu(NO(3))(C(10)H(8)N(2))(2)]ClO(4), the five-coordinated Cu(II) atom has a distorted square-pyramidal CuN(4)O environment; the O atom is in the axial position whereas the N atoms from two bipyridine (bipy) ligands are in the equatorial plane. In the crystal, mol-ecules are assembled by C-H⋯O hydrogen bonding and π-π inter-actions between bipy groups [centroid-centroid distances = 3.7686 (16) and 3.7002 (16) Å] into a three-dimensional network. The nitrite anion is equally disordered over two sets of sites.

(2,2'-Bipyridine-κN,N')bis-(4-chloro-benzoato-κO)zinc.

Project description:In the title compound, [Zn(C(7)H(4)ClO(2))(2)(C(10)H(8)N(2))], the Zn(II) atom is coordinated by two O atoms from two 4-chloro-benzoate ligands and two N atoms from a chelating 2,2'-bipyridine (bpy) mol-ecule in a distorted N(2)O(2) tetra-hedral geometry. The Zn(II) atom is located on a twofold rotation axis, which also passes through the mid-point of the central C-C bond of the bpy ligand. In the crystal, weak C-H⋯O hydrogen bonds and π-π stacking inter-actions between the pyridine rings of the bpy ligands [centroid-centroid distance = 3.642 (3) Å] link the complex mol-ecules into a two-dimensional supra-molecular structure parallel to (100).

Bis(2,2'-bipyridine-κN,N')(croconato-κO,O')nickel(II).

Project description:The title compound, [Ni(C(5)O(5))(C(10)H(8)N(2))(2)], lies across a crystallographic twofold axis, around which two 2,2'-bipyridine (2,2'-bipy) ligands are arranged in a propeller manner. The local geometry of the NiN(4)O(2) coordination core basically adopts an octa-hedral geometry. The mol-ecular twofold axis is along the direction of the mol-ecular dipole moment, and the complex is packed with its dipole moment alternately along the +b and -b directions. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

Project description:The central CuN(2)O(4) motif of the title compound, [Cu(ClO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal atom, showing a considerably long Cu-O bond distance of 2.5058 (12) Å towards the second perchlorate group, giving a (4 + 1+1)-type coordination mode. In the crystal, the components are linked via inter-molecular O-H⋯O hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by π-π [centroid-centroid distances of 3.7848 (9)-4.4231 (9) Å] stacking inter-actions.

One of the methyl groups is disordered over two positions in a 0.536 (11):0.464 (11) ratio.

catena-Poly[[bis-(2,2'-bipyridine-κN,N')cadmium(II)]-μ-9,10-dioxo-anthracene-1,5-disulfonato-κO:O].

Project description:The title complex, [Cd(C(14)H(6)O(8)S(2))(C(10)H(8)N(2))(2)](n), exhibits a chain-like polymeric structure with 9,10-dioxoanthracene-1,5-disulfonate anions bridging Cd(II) atoms in a bis-monodentate mode. The Cd(II) atom shows a distorted octa-hedral environment, with four N atoms from two chelating 2,2'-bipyridine ligands forming the equatorial plane and two sulfonate O atoms from two 9,10-dioxoanthracene-1,5-disulfonate anions occupying the apical positions. Weak C-H⋯O hydrogen-bonding contacts and π-π inter-actions [centroid-centroid distances = 3.6920 (12) and 3.7095 (12) Å] connect the complex mol-ecules into a three-dimensional supra-molecular framework.
