Poly[μ-aqua-diaqua-(μ(3)-N'-carboxy-methyl-ethylenediamine-N,N,N'-tri-acetato)oxidopotassium(I)vanadium(IV)].

ABSTRACT: In the crystal structure of the title compound, [KV(C(10)H(13)N(2)O(8))O(H(2)O)(3)](n), the V(IV) ion adopts a distorted octa-hedral geometry, coordinated by one oxide group, two N and three carboxylate O atoms from the same N'-carboxy-methyl-ethyl-ene-diamine-N,N,N'-triacetate (HEDTA) ligand. The potassium ion is hepta-coordinated by two water mol-ecules, two bridging water mol-ecules and three carboxylate O atoms from three neighbouring HEDTA ligands. The HEDTA ligands and some of the water mol-ecules act as bridges, linking the compound into a three-dimensional architecture via 2(1) screw, c-glide, translation and inversion symmetry operators. Meanwhile, three types of O-H⋯O hydrogen bonds provide an additional stabilization of the three-dimensional architecture.

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.

Project description:The title compound, {[La(4)(CH(3)CO(2))(10)(C(2)O(4))(H(2)O)(2)]·2H(2)O}(n), exhibits a two-dimensional layered structure with the oxalate and acetate ligands acting as bridges. The asymmetric unit contains two crystallographically independent lanthanum(III) ions, half of an oxalate ligand, five acetate ligands, one coordinated water mol-ecule and one uncoordinated water mol-ecule. The coordination numbers of the two La ions are 9 and 10.

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[μ-aqua-diaqua-(μ(2)-pyrazine-2,3-dicarboxyl-ato)dilithium(I)].

Project description:The asymmetric unit of the title compound, [Li(2)(C(6)H(2)N(2)O(4))(H(2)O)(3)](n), consists of two independent Li(+) cations, one pyrazine-2,3-dicarboxyl-ate dianion and three water mol-ecules. One of the Li(+) cations has a distorted tetra-hedral geometry, coordinated by one of the carboxyl-ate O atoms of the pyrazine-2,3-dicarboxyl-ate ligand and three O atoms from three water mol-ecules, whereas the other Li(+) cation has a distorted trigonal-bipyramidal geometry, coordinated by a carboxyl-ate O atom of a symmetry-related pyrazine-2,3-dicarboxyl-ate ligand, two water mol-ecules and a chelating pyrazine-2,3-dicarboxyl-ate ligand (by utilizing both N and O atoms) of an adjacent mol-ecule. The synthesis of a hydrated polymeric dinuclear lithium complex formed with two pyrazine-2,3-dicarboxylic acid ligands has been reported previously [Tombul et al. (2008a ▶). Acta Cryst. E64, m491-m492]. By comparision to the complex reported here, the dinuclear complex formed with two pyrazine-2,3-dicarboxylic acid ligands differs in the coordination geometry of both Li atoms. The crystal structure further features O-H⋯O and O-H⋯N hydrogen-bonding inter-actions involving the water mol-ecules and carboxyl-ate O atoms.

Project description:In the title compound, [CuK(2)(C(3)N(2)O(3))(2)(H(2)O)(3)](n), the Cu(2+) atom is in a distorted square-pyramidal coordination geometry. Two N atoms belonging to the oxime groups and two O atoms belonging to the carboxyl-ate groups of two trans-disposed doubly deprotonated residues of 2-cyano-2-(hy-droxy-imino)-acetic acid make up the basal plane and the apical position is occupied by the water mol-ecule. The neighboring Cu-containing moieties are linked into a three-dimensional framework by K-O and K-N contacts formed by two potassium cations with the carboxyl-ate and the oxime O atoms and the nitrile N atoms of the ligand. The environments of the K(+) cations are complemented to octa- and nona-coordinated, by K-O contacts with H(2)O mol-ecules. The crystal structure features O-H⋯O hydrogen bonds.

Project description: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.
