Poly[di-?-aqua-diaqua-di-?(6)-malonato-cobalt(II)dipotassium(I)].

ABSTRACT: In the title complex, [CoK(2)(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Co atom is located on a position with site symmetry 2/m, the K atom and one water mol-ecule are located on a mirror plane, and the malonate and one water mol-ecule are located on a twofold rotation axis. The K(I) atom is seven-coordinated by four carboxyl-ate O atoms from four malonate ligands and by three water O atoms, forming a distorted polyhedron. The Co(II) atom is in an almost octa-hedral environment formed by four carboxyl-ate O atoms from two malonate ligands and two water O atoms. The structure consists of layers parallel to (20[Formula: see text]) built up from edge-sharing KO(7) and CoO(6) polyhedra, which are connected by O-H?O hydrogen bonding including water mol-ecules into a three-dimensional network.

Poly[tetra-aqua-di-μ(4)-malonato-barium(II)cadmium(II)].

Project description:In the title complex, [BaCd(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Ba(II) atoms, located on crystallographic twofold axes, adopt slightly distorted square-anti-prismatic coordination geometries, while the Cd(II) atoms, which lie on crystallographic centres of symmetry, have a distorted octa-hedral coordination. Each malonate dianion binds two different Cd(II) atoms and two different Ba(II) atoms. This connectivity generates alternating layers along [100] in the structure, with one type containing Cd(II) cations and malonate dianions, while the other is primarily composed of Ba(II) ions and coordinated water mol-ecules. The water mol-ecules also participate in extensive O-H⋯O hydrogen bonding.

Poly[tri-μ-aqua-di-aqua-μ-phosphono-formato-cobalt(II)sodium].

Project description:The title complex, [CoNa(CO5P)(H2O)5]n, was obtained by reacting sodium phosphono-formate with cobalt nitrate. The complex contains cobalt(II) and sodium ions, which are bridged by the O atoms of two aqua ligands. The Co(II) ion is octahedrally coordinated by three phosphonoformato ligands (one bi- and the other monodentate) and by two O atoms from the bridging aqua ligands. The sodium cation is hexa-coordinated by six O atoms from four bridging and two terminal aqua ligands. The complex mol-ecules are linked to give a three-dimensional structure by phosphono-formate ligands bridging Co(II) atoms and water mol-ecules establishing cobalt-sodium bridges. O-H⋯O hydrogen bonding between the aqua ligands and all O atoms of the phosphono-formato ligand and neighbouring aqua ligands help to consolidate the packing.

Poly[diaqua-μ(4)-oxalato-di-μ(6)-phosphato-tetra-cobalt(II)].

Project description:In the structure of the title compound, [Co(4)(C(2)O(4))(PO(4))(2)(H(2)O)(2)](n), there are layers composed of the phosphate anions and two independent Co(II) cations. These layers are parallel to (001) and are bridged by the oxalate anions that are situated in special positions on centres of symmetry. One independent Co atom has an octa-hedral coordination, while the second independent Co atom is coordinated in a trigonal-bipyramidal coordination that includes the water mol-ecule. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and oxalate O atoms.

Poly[diaqua-tetra-μ-seleno-cyanato-cadmium(II)dipotassium(I)].

Project description:In the title compound, [CdK(2)(NCSe)(4)(H(2)O)(2)](n), the cadmium(II) cation is situated on a twofold rotation axis and is coordinated in a slightly distorted tetra-hedral geometry by two symmetry-related μ-1,1,1,3 and two-symmetry related μ-1,1,3,3 bridging seleno-cyanate anions, all of which are Se bonded. These bridging seleno-cyanate anions are further coordinated to two symmetry-related potassium ions. Each of the potassium ions is coordinated by one terminally bonded water mol-ecule and six seleno-cyanate anions, two of which are crystallographically independent. The asymmetric unit consists of one cadmium and one potassium cation, two bridging seleno-cyanate anions and one water mol-ecule. The polymeric subunits are further connected via the seleno-cyanate anions into a three-dimensional coordination network. In this coordination network, intramolecular hydrogen bonds between neighbouring water molecules can be found.

Poly[μ-aqua-di-μ-benzoato-lead(II)].

Project description:The reaction of lead(II) nitrate and benzoic acid in aqueous solution yields the title polymer, [Pb(C(7)H(5)O(2))(2)(H(2)O)](n). The asymmetric unit contains one Pb(II) ion, two benzoate ligands and one water mol-ecule. The Pb-O bond distances are in the range 2.494 (4)-2.735 (4) Å. The Pb⋯Pb distance is 4.0683 (4) Å, indicating an insignificant metal-metal inter-action. The Pb(II) atom has a distorted penta-gonal-bipyramidal geometry chelated by two carboxyl-ate O atoms. The Pb atoms are bridged through a coordinating water mol-ecule and two carboxyl-ate O atoms from another two benzoate ligands, giving an infinite three-dimensional supra-molecular structure. O-H⋯O hydrogen-bonding inter-actions involved the coordinating water and carboxyl-ate O atoms enhance the stability of the supra-molecular arrangement.

Poly[hexa-aqua-tri-μ-malonato-didysprosium(III)].

Project description:The title compound, [Dy(2)(C(3)H(2)O(4))(3)(H(2)O)(6)](n), forms a coordination polymeric structure comprising hydrated dysprosium ions and malonate ligands. In the asymmetric unit, there are one dysprosium ion, one and a half malonate ligands, and three water mol-ecules. Each Dy(III) atom is coordinated by six O atoms from four malonate ligands and by three water mol-ecules, and displays a tricapped trigonal-prismatic coordination geometry. The malonate ligands adopt two types of coordination mode, linking dysprosium centres to form a three-dimensional coordination polymer. The extensive network of hydrogen bonds in this polymer enhances the structural stability.

Poly[[[tetra-aqua-cobalt(II)]-μ-bipyridine] terephthalate].

Project description:The Co(II) atom in the title complex, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4))}(n), is coordinated by two N atoms of two bipyridine ligands and four O atoms of four water mol-ecules in an octahedral geometry. The one-dimensional [Co(C(10)H(8)N(2))(H(2)O)(4)](2+) cation chain is further extended into a supra-molecular network via O-H⋯O hydrogen-bond inter-actions. The Co atom lies on a twofold rotation axis; another twofold rotation axis passes through the carboxylate carbon atoms and the attached ring C atoms.

Poly[diaqua-di-μ(4)-citrato-trizinc(II)].

Project description:The title compound, [Zn(3)(C(6)H(5)O(7))(2)(H(2)O)(2)](n), is a polymer in which the repeating unit contains three zinc atoms, two hepta-dentate Hcit ligands (Hcit = citric acid trianion) and two coordinated water mol-ecules, only half of which are independent due to one of the metal atoms lying on a centre of symmetry. The two independent cations both exhibit an octa-hedral geometry, but the way in which they are coordinate are different; while the Zn atom in a general position is bound to three Hcit ligands and one water mol-ecule, the one at the centre of symmetry is coordinated by six O atoms from two symmetry-related Hcit ligands through the (protonated) hydroxyl and carboxyl-ate groups. The three carboxyl-ate groups coordinate to the Zn centres in three different ways, viz. chelating, bridging and a mixture of both, in an unusual coordination mode for citrate. The result is a two-dimensional structure parallel to (010), built up by a square-grid motif. Intermolecular O-H⋯O hydrogen bonds are present in the crystal structure.

Di-μ-acetato-μ-aqua-bis-[acetatobis(1H-benzimidazole)cobalt(II)].

Project description:In the title compound, [Co(2)(C(2)H(3)O(2))(4)(C(7)H(6)N(2))(4)(H(2)O)], the half-mol-ecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full mol-ecule. The Co(II) ions are approximately octahedrally coordinated with a cis-N(2)O(4) coordination sphere. The compound features intra-molecular O-H⋯O hydrogen bonds between the non-bridging acetate groups and the bridging water mol-ecule, and inter-molecular N-H⋯O hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the mol-ecular packing in the crystal structure.

Project description:In polymeric title compound, {[Co(2)(C(7)H(2)N(2)O(7))(2)(H(2)O)(6)]·2H(2)O}(n), obtained from the reaction of 3,5-dinitro-salicylic acid with cobalt(II) acetate, both Co(II) atoms are located on inversion centres and exhibit a distorted octahedral coordination geometry. The coordin-ation sphere about one Co(II) atom comprises four O-atom donors from two bidentate chelate (O(phenolate) and O(carbox-yl)) and bridging dianionic ligands and two water mol-ecules [Co-O range = 2.0249 (11)-2.1386 (14) Å], while that about the second Co(II) atom has four water mol-ecules and two bridging carboxyl-ate O-donor atoms [Co-O range = 2.0690 (14)-2.1364 (11) Å]. The coordinated water mol-ecules as well as the water mol-ecules of solvation give O-H⋯O water-water and water-carboxyl hydrogen-bonding inter-actions in the three-dimensional framework structure.
