Synthesis,Crystal Structure and Electrochemistry of Two Complexes （YLn）3＋[PW12O40]3-（L=Me2SO,Me2NCHO）

The reaction of α-H3[PW12O40] with Y（NO3）3 in the presence of DMF or DMSO leads to two complexes with the formulae {Y（DMSO）7}·PW12O40（1） and {[Y（DMF）7]2PW12O40}·PW12O40（2）. The crystal structures indicate that complex 1 consists of discrete [YLn]3＋ cations and α-Keggin heteropolyanions [PW12O40]3-, whereas, in complex 2, donor-acceptor interaction results in a cation-anion-cation triplet. In addition, the electrochemical behavior of the two complexes indicates the usual successive reduction processes of the W atoms in the anions.

Hydrothermal Synthesis and Crystal Structure of a Polyoxometalate- based Complex [Cu^I（phen）2]4（SiW12O40）

A new hybrid polyoxometalate-based complex, [Cu^I（phen）214（SiW12O40） （phen = 1,10-phenanthroline）, has been synthesized by hydrothermal method and characterized with the aid of elemental analysis, IR, UV spectra and thermal analysis studies. The result of X-ray crystallography analysis exhibits that the title compound crystallizes in the orthorhombic space group P212121, and the formula is C96H64N16Cu4SiW12O40. Crystal data： a = 18.3574（14）, b = 21.1952（16）, c = 27.992（2）A, Mr = 4570.08, V = 10891.4（14）A^3, Z = 4, Dc = 2.787 g/cm^3,μ = 13.478 mm^-1, R = 0.0364, wR = 0.0638 （I 〉 2σ（I）） and F（000） = 8360. The complex consists of one α-Keggin anion [SIW12O40]^4- and four discrete [Cu^I（phen）2]^＋ cations. The valence sum calculations for the Cu atoms suggest that all four Cu atoms are in the ＋1 oxidation state.

Synthesis and Crystal Structure of a New Mixed-ligand Cluster [Mo3O4（C2O4）2bipy-（H2O）3]·EtOH·2H2O（bipy = 2,2′-Bipyridine）

The novel mixed-ligand neutral compound [Mo3O4（C2O4）2bipy-（H2O）3]·EtOH·2H2O（bipy = 2,2′-bipyridine） has been prepared by the reaction of oxalic acid elution of Mo（IV） and bipy, and characterized by single-crystal X-ray diffraction analysis and IR. The crystal is of triclinic, space groups P1^- with a = 9.5520（2）, b = 10.3730（1）, c = 13.5722（2）A, a = 74.940（12）,β = 80.772（14）,γ= 69.898（11）°, V = 1215.73（11）A^3, Z = 2, C16H24Mo3N2O18, Mr = 820.19, Dc = 2.241 g/cm^3,μ = 1.616 mm^-1, F（000） = 808, T = 293（2） K, the final R = 0.0424 and wR = 0.0939 for 4119 observed reflections with I 〉 2σ（I）. The trinuclear unit is coordinated by mixed ligands of oxalate and bipy. The intermolecular hydrogen bonding interactions among adjacent [Mo3O4（C2O4）2·bipy（H2O）3] extend the compound into a three-dimensional supramolecular framework. The uncoordinated water molecules and ethal molecules act as space-fillers and consolidate the whole architecture through hydrogen bonding interactions.     

Synthesis and Crystal Structure of a 1-D Coordination Polymer [Pb（ANS）2（phen）]n

A new one-dimensional coordination polymer, [Pb(phen)(ANS)2]n (ANS = 2-ami- nonaphthalene-1-sulfonate, phen = 1,10-phenanthroline), has been prepared by hydrothermal synthesis and structurally characterized by elemental analysis, IR and single-crystal X-ray diffrac- tion. The results determined by XRD reveal that the complex crystallizes in monoclinic, space group P21/c with a = 16.8374(14), b = 16.9825(14), c = 9.9392 (8) , β = 95.9830(10)o, V = 2826.5(4) 3, Mr = 831.86, Dc = 1.955 g/cm3, μ(MoKα) = 6.173 mm-1, F(000) = 1624, Z = 4, the final R = 0.0272 and wR = 0.0694 for 4305 observed reflections (I > 2σ(I)). In the complex, the adjacent lead(II) ions are bridged through the oxygen atoms of sulfonate groups in a syn-syn conformation, yielding an infinite zigzag chain. And the intermolecular N–H···O hydrogen bonds link the chains into two-dimensional layered networks, which are further assembled into a separate two-layer-film-like packing structure.

A novel complex Zn(phen)(m-CBA)2(H2O) with m-chlorobenzoic acid (m-CBA), 1,10-phenanthroline (phen) and zinc chloride has been hydrothermally synthesized and characterized. Crystal data for this complex: triclinic, space group P1, a = 0.8361(5), b = 1.2455(7), c = 1.3107(7) nm, α = 115.637(8), β = 91.014(9), γ = 104.857(8)o, V = 1.1763(11) nm3, Dc = 1.623 g/cm3, Z = 2, F(000) = 584, GOOF = 1.078, the final R = 0.0453 and wR = 0.1192. Structure analysis shows that the zinc ion coordinates with two nitrogen atoms of one 1,10-phenanthroline molecule, three oxygen atoms from two m-chlorobenzoic acid molecules and one water molecule, giving a distorted square-pyramidal coordination geometry. The cyclic voltametric behavior of the complex was also investigated.
