Poly[aqua-hexa-benzimidazole-octa-?-cyanido-octa-cyanidotricopper(II)ditungstate(V)].

ABSTRACT: In the polymeric title compound, [Cu(3)W(2)(CN)(16)(C(7)H(6)N(2))(6)(H(2)O)](n), the coordination geometry of the W(V) atom is eight-coordinate dodeca-hedral, where four CN groups of [W(CN)(8)] are bridged to Cu(II) ions, and the other four CN groups are not bridged. The coordination geometries of the Cu(II) ions are five-coordinate pseudo-square-based pyramidal. There are two distinct Cu sites, which build and link the cyanido-bridged Cu-W ladder chains. Successive connections lead to the formation of a two-dimensional network. The H atoms of a coordinated water molecule and the imino groups form hydrogen bonds to the N atoms of non-bridged CN groups.

Project description:The structure of the title compound, Mn(II)[Fe(III)(CN)(6)](2/3)·5H(2)O, features a face-centered cubic -Mn-NC-Fe- framework with both Mn and Fe having site symmetry mm. Since one-third of the [Fe(CN)(6)](3-) units are missing for a given formula in order to maintain charge neutrality, each Mn atom around such a vacancy is coordinated not only by the N atoms of the CN groups but also by the O atoms of the ligand water mol-ecules. In addition to ligand water mol-ecules, two types of non-coordinated water mol-ecules, so-called zeolitic water mol-ecules, exist in the inter-stitial sites of the -Mn-NC-Fe- framework. The positions of the O atoms of the zeolitic water mol-ecules are fixed by the linkage via hydrogen bonds between ligand water and zeolitic water mol-ecules. The structure is related to a recently reported rubidium manganese hexa-cyano-ferrate. Site occupancy factors for Fe, C, N are 0.67; for two O atoms the value is 0.83 and for one O atom is 0.17.

Poly[[tri-μ-cyanido-cyanido(1,4,10,13-tetra-oxa-7,16-diaza-cyclo-octa-deca-ne)barium(II)platinum(II)] hemihydrate].

Project description:The title compound, {[BaPt(CN)(4)(C(12)H(26)N(2)O(4))]·0.5H(2)O}(n), is a two-dimensional coordination polymer in which the sheets are oriented approximately parallel to the (01) set of crystal planes. In the crystal structure, disordered water mol-ecules (half occupancy) connect the sheets into a three-dimensional network via inter-molecular O-H⋯O hydrogen bonds. An N-H⋯N inter-action is also present. The shortest Pt⋯Pt contacts are 7.5969 (4) Å by an inversion relationship and 7.6781 (4) Å by translation along the a axis.

Poly[hexa-aqua-(μ9-cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ato)trimanganese(II)].

Project description:The asymmetric unit of the title compound, [Mn3(C12H6O12)(H2O)6] n , comprises one Mn(II) ion, one third of a cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate anion and two aqua ligands. The anion is completed by application of a -3 axis. The Mn(II) ion is six-coordinated by six O atoms from two aqua ligands and three different cyclo-hexa-carboxyl-ate anions in an octa-hedral geometry. The six carboxyl-ate groups adopt a bridging bidentate mode to ligate the Mn(II) ions. Thus, each cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate anion adopts a μ9-connected mode, ligating nine different Mn(II) ions and forming a three-dimensional framework. In the framework, there are strong O-H⋯O hydrogen-bonding inter-actions, which further stabilize the crystal structure.

Crystal structure of poly[[di-aqua-tetra-μ2-cyanido-iron(II)platinum(II)] acetone disolvate].

Project description:In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octa-hedral [FeN4O2] geometry being coordinated by two water mol-ecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetra-cyano-platinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest mol-ecules of acetone per FeII are located between the layers. These guest acetone mol-ecules inter-act with the coordinated water mol-ecules by O-H⋯O hydrogen bonds.

Poly[hexa-aqua-hexa-kis-(?-pyridine-2,4-dicarboxyl-ato)tricopper(II)dieuropium(III)].

Project description:The asymmetric unit of the title heterometallic coordination polymer, [Cu(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(6)](n), contains one Eu(III) and two Cu(II) atoms, three pyridine-2,4-dicarboxylate (pdc)(2-) anions and three water molecules. One Cu(II) atom is located on an inversion center and is N,O-chelated by two pdc(2-) anions in the equatorial plane and further coordinated by two carboxyl-ate O atoms from another two pdc anions in the axial positions, with an elongated octa-hedral geometry [Cu-O = 2.409?(3)?Å in the axial direction]; the other Cu atom is N,O-chelated by two pdc anions in the coordination basal plane and coordinated by a carboxyl O atom at the apical position with a distorted square-pyramidal geometry [Cu-O = 2.359?(3)?Å in the apical direction]. The Eu atom is eight-coordinated with a distorted square-anti-prismatic geometry formed by five carboxyl-ate O atoms from five pdc anions and three water mol-ecules. The carboxyl-ate anions bridge adjacent Eu and Cu atoms, forming the coordination polymer. Inter- and intra-molecular O-H?O hydrogen bonding occurs in the structure. ?-? stacking further consolidates the crystal structure, the centroid-centroid distance between parallel pyridine rings being 3.367?(2)?Å.

Project description:In the title complex, [Mn(C(9)H(4)N(2)O(4))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination completed by one N atom from one 1H-benzimidazole-5,6-dicarboxyl-ate ligand, two O atoms from two different 1H-benzimidazole-5,6-dicarboxyl-ate ligands, and three O atoms from three water mol-ecules. Two bridging water mol-ecules and two bridging carboxyl-ate groups from a 1H-benzimidazole-5,6-dicarboxyl-ate ligand connect two Mn(II) ions into a dimeric structure. In the crystal, extensive inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonding forms a three-dimensional network.

Poly[[diaqua-hexa-?-cyanido-cerium(III)ferrate(III)] dihydrate].

Project description:In the structure of the title complex, {[CeFe(CN)(6)(H(2)O)(2)]·2H(2)O}(n), the Ce(III) and Fe(III) atoms exhibit square anti-prismatic [CeN(6)(H(2)O)(2)] (site symmetry m2m) and octahedral [FeC(6)] (site symmetry 2/m) coordination geometries, respectively. The metal atoms are linked alternately through the cyanide groups, forming a three-dimensional framework in which the {Ce(2)Fe(2)(CN)(4)} puckered square unit is the basic building block. The crystal packing is enforced by O-H?O and O-H?N hydrogen bonds, including the uncoordinated water molecule which is located on a mirror plane.
