Catena-Poly[[bis-(acetato-?O)aqua-copper(II)]-?-5-(pyridin-3-yl)pyrimidine-?N:N].

ABSTRACT: In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157?(2)?Å and the Cu(II) ion is displaced by 0.050?(3)?Å from this plane towards the apical water O atom. Bridging through the bis-monodentate 5-(pyridin-3-yl)pyrimidine ligand forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure parallel to (100). The crystal studied was an inversion twin with a 0.57?(3):0.43?(3) domain ratio.

catena-Poly[[[di-aqua-bis-[1,2-bis-(pyridin-4-yl)diazene]copper(II)]-μ-1,2-bis-(pyridin-4-yl)diazene] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via azo bonds which are situated about inversion centres. Since the Cu(II) atom is situated on a twofold rotation axis, the monomeric unit has point symmetry 2. The perchlorate anions are disordered in a 0.536 (9):0.464 (9) ratio and are acceptors of water H atoms in medium-strong O-H⋯O hydrogen bonds with graph set R 4 (4)(12). The water mol-ecules, which are coordinated to the Cu(II) atom and are hydrogen-bonded to the perchlorate anions, form columns parallel to [010]. A π-π inter-action [centroid-centroid distance = 3.913 (2) Å] occurs between pyridine rings, and weak C-H⋯O inter-actions also occur.

Project description:In the title complex, {[Cd(CH(3)COO)(2)(C(11)H(8)N(2)O)(H(2)O)]·2H(2)O}(n), the Cd(II) ion adopts an O(5)N(2) penta-gonal-bipyramidal coordination geometry with four acetate O atoms and one water O atom at the equatorial sites and two pyridine N atoms at the axial sites. The (pyridin-3-yl)(pyridin-4-yl)methanone ligand acts in a ?(2)-bridging mode, linking the metal atoms, leading to an infinite chain along [-110]. O-H?O hydrogen bonds involving the lattice water mol-ecules connect these chains into a three-dimensional network.

Project description:The crystal structure of the title compound, {[Na(C(7)H(5)ClNO(2))(H(2)O)(3)]·H(2)O}(n), features polymeric chains along [010].

Project description:The crystal structure of the title complex, [Zn(C(7)H(6)NO(2)S)(2)(H(2)O)](n), consists of extended layers parallel to (001) with 2-(pyridin-4-ylsulfan-yl)acetate ligands bridging the Zn(II) atoms. The Zn(II) atom shows a distorted penta-gonal-bipyramidal coordination environment. The Zn(II) and one O atom are situated on a crystallographic twofold rotation axis. In the crystal, intra-layer O-H?O hydrogen-bond inter-actions help to consolidate the coordination layer.

catena-Poly[[[aqua-copper(II)]-bis-[?-N,N'-bis-(pyridin-4-yl)isophthalamide]-[aqua-copper(II)]-di-?-sulfato] dimethyl-formamide disolvate].

Project description:In the title coordination polymer, {[Cu(SO4)(C18H14N4O2)(H2O)]·C3H7NO} n , the Cu(II) ion is coordinated by two N atoms of two briding N,N'-bis-(pyridin-4-yl)isophthalamide ligands, two O atoms of two bridging SO4(2-) anions and a water mol-ecule, giving a distorted CuN2O3 square-pyramidal geometry. The whole repeating mol-ecular unit is generated by inversion symmetry. This leads to the formation of a looped-chain one-dimensional coordination polymer propagating along [110]. The dimethyl-formamide (DMF) mol-ecules are linked to the chains via O-H?O hydrogen bonds. The chains are linked via N-H?O hydrogen bonds, forming two-dimensional networks parallel to (001). There are also a number of C-H?O inter-actions present and a parallel slipped ?-? inter-action. The latter involves inversion-related pyridine rings with a centroid-centroid distance of 3.594?(2)?Å [normal distance = 3.3338?(13) and slippage = 1.341?Å]. These inter-actions lead to the formation of a three-dimensional structure.

catena-Poly[[diaqua-nickel(II)]-bis-(μ-2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfan-yl}acetato)].

Project description:In the title compound, [Ni(C(9)H(6)N(3)O(3)S)(2)(H(2)O)(2)](n), the Ni(II) atom, located on an inversion center, is ligated in an octa-hedral geometry by two carboxyl-ate O atoms from two 2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfan-yl}acetate (L) ligands and two O atoms from water mol-ecules in the equatorial plane, and two pyridine N atoms from other two L ligands at the apical sites. Two L ligands bridge pairs of metal atoms in an anti-parallel manner, forming centrosymmetric dinuclear quasi-recta-ngular units which are linked into infinite double-stranded chains parallel to [100]. O-H⋯O hydrogen bonds between the coordinating water mol-ecules and the carboxyl-ate groups of the L ligand as well as interchain S⋯N inter-actions [2.726 (2)-3.363 (2) Å] lead to the formation of a layer structure parallel to (001).

catena-Poly[[[di-aqua-cobalt(II)]-bis-{?-2-[3-(4-carboxyl-atophen-yl)pyridin-1-ium-1-yl]acetato}] dihydrate].

Project description:In the title polymeric coordination compound, {[Co(C14H10NO4)2(H2O)2]·2H2O} n , the Co(II) ion resides on an inversion center and exhibits a distorted o-cta-hedral coordination geometry defined by four O atoms from two pairs of equivalent monodentate carboxyl-ate groups from 2-[3-(4-carboxyl-atophen-yl)pyridin-1-ium-1-yl]acetate ligands and by two O atoms from two equivalent coordinating water mol-ecules. The zwitterionic di-carboxyl-ate ligands serve as bridges with two monodentate carboxyl-ate and the metal ions are linked by double bridges, forming polymeric chains running along [01-1]. The chains are further stabilized and associated into layers parallel to (011) through intra- and inter-chain hydrogen bonding and ?-? stacking inter-actions [inter-planar and centroid-centroid distances of 3.658?(3)?Å and 3.653?(2)?Å, respectively].

Project description:In the title compound, {[Cu(C(10)H(14)N(4)Se)(2)(H(2)O)]Cl(2)·H(2)O}(n), the Cu(II) ion, lying on a twofold rotation axis, has a square-pyramidal geometry constituted by four N atoms of pyrazolyl groups in the basal plane and an apical O atom of a water mol-ecule. A pair of bis-(3,5-dimethyl-1H-pyrazol-4-yl) selenide ligands bridge the Cu centers into a polymeric double-chain extending along [001]. The chloride anions are involved in inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds, which link the chains into a three-dimensional network.
