One novel coordination polymer {[Co(4,4′-bipy)(C9H8O3N)2](H2O)4}n with p-acetamidobenzoic acid and 4,4′-bipy has been synthesized. It was characterized as crystallizing in the triclinic space group P1, with: a=1.138 1(2) nm, b=1.165 2(2) nm, c=1.223 3(2) nm, α=88.47(3)°, β=88.00(3)°, γ=65.78(3)°, V=1.478 4(4) nm3, Dc=1.446 g·cm-3, Z=1, F(000)=670. Final GooF=1.106, R1=0.041 5, wR2=0.110 4. The crystal structure shows that the cobalt(Ⅱ) ion is lined with one 4,4′-bipy molecule, forming a one-dimension chain with Z-type structure, which coordinated with two nitrogen atoms of two 4,4′-bipy molecules and four oxygen atoms from two p-acetamidobenzoic acid molecules, giving a distorted octahedral coordination geometry. The result of TG analysis shows that the title complex was stable under 230.0 ℃. CCDC: 741932.  相似文献

The complex {[Co(4,4′-bpy)(H2O)4](Fum)·4H2O}n(where 4,4′-bpy = 4,4′-bipyridine and Fum = fumarate) was synthesized and characterized by X-ray diffraction. The complex consists of one-dimensional chains containing cobalt(Ⅱ) ions bridged by 4,4′-bpy molecules. The six-coordination of Co2+ is achieved by means of four water molecules. The fumarate is not coordinated to cobalt ion while it forms hydrogen bonds with coordinated and non-coordinated water molecules and extends the structure into three-dimensional hydrogen bonding network.

One dimensional chain cobalt coordination polymer has been synthesized with malic acid and cobalt(Ⅱ) chloride anhydrous, and characterized by the element analysis, IR, TGA and single crystal X-ray diffraction structure analysis. The title complex crystallizes in monoclinic system with space group P21, a=0.575 61(9) nm, b=0.905 86(14) nm, c=0.841 02(13) nm, β=105.350(2)°; V=0.422 88(11) nm3, Z=2, Dc=1.924 Mg·m-3, μ=2.044 mm-1, F(000)=250, and final R1=0.029 3, wR2=0.074 2. The crystal structure shows that the cobalt ion is coordinated with four oxygen atoms from two different malate molecules and two oxygen atoms from two water molecules respectively, forming a distorted octahedral coordination geometry. Two adjacent cobalt(Ⅱ) atoms are bridged by one malate groups in bis-monodentate mode, constructing a one dimensional chain structure along b axis, with the adjacent Co…Co distance being 0.530 9 nm. Moreover, the molecules are packed in three-dimensional supramolecular network though the intermolecular hydrogen bonds. CCDC: 704441.  相似文献

The novel coordination polymer {[Cd(p-CMSP)(Him)(H2O)]·3H2O}n ( p-CMSP2-=p-(carboxymethoxy)phenylthioacetate, Him=imidazole) was synthesized by the reaction of Cd(NO3)2, imidazole and p-(carboxymethoxy)phenylthioacetic acid in an aqueous solution, and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. The crystal structure is of monoclinic, space group P21/c with a=1.144 0(2) nm, b=1.876 7(4) nm, c=0.877 89(18) nm, β=106.31(3)° and V=1.808 9(7) nm3, Z=4, R=0.023 2, wR=0.051 4. Each Cd(II) atom displays a distorted octahedral coordination geometry, defined by three carboxyl O atoms from different p-CMSP2- ligands, one S atom from thioether, one N atom from imidazole and one water molecule. Adjacent Cd(II) ions are bridged by p-CMSP2- groups, resulting in a 2D layer structure. The adjacent Cd…Cd distances are 0.492 7 nm and 1.144 0 nm. Furthermore, such layers are linked through hydrogen bonds to form supramolecular network. CCDC: 269474.  相似文献

A novel one-dimensional chain coordination polymer [Mn(NAAh(4,4′-bipy)(H2O)4], has been synthesized with a-naphthaleneacetic acid, 4,4′-bipy and manganese(Ⅱ) sulfate as raw materials. Crystal data for this complex: monoclinic, space group P21/c, a = 1.1421(2), b = 1.6337(3), c = 0.94177(19) nm, β = 112.15(3)°, V = 1.6275(6) nm^3, De = 1.407 g/cm^3, Z = 2, μ(MoKa) = 0.467 mm^-1, F(000) = 722, S = 1.007, R= 0.0412 and wR = 0.1022. The crystal structure shows that two neighboring manganese(Ⅱ) ions are linked together by one 4,4′-bipy molecule, and the whole complex molecule forms a one-dimensional chain structure. Each manganese(Ⅱ) ion is coordinated with two oxygen atoms of two a-naphthaleneacetic acid molecules, two nitrogen atoms of two 4,4′-bipy molecules and two oxygen atoms from two water molecules, giving a distorted octahedral coordination geometry. The electrochemical properties were also analyzed.  相似文献
