A novel series of Keggin species with a covalently bonding support-ligand, formulated α-[SiW11O39M(H2PO4)]n- (M = CoII, MnII, NiII or CrIII), have been synthesized and characterized by elemental analyses, IR, CV, NMR and X-ray powder diffraction measurements. The structure is reminiscent of an ancient Chinese three-legged wine vessel, and is a possible model for POM-nucleotide interaction. An interesting property is the different thermal behaviors for this series in comparison with those for corresponding 3d metal monosubstituted Keggin polyoxometalates. This can be attributed largely to the pendant surface ligand and H bonding interaction. Compared with α-PW11M, the orders of line broadening of 31P NMR signals are the same for the two series of complexes α-PW11M and α-SiW11M-PO4, but both contact and dipolar interactions might make a significant contribution to the chemical shift for phosphorus for the latter.

Novel Keggin anions with covalently bonding pendant surface ligands, formulated as [SiW11O39M(H3P2O7)]7-, (M =MnII, CoII, NiII and ZnII), were synthesized, and characterized by elemental analyses and IR, CV and NMR physical measurements. The novel complexes are expected to have the ability to anchor the clusters on supports via terminal phosphato group-support linkages.

A new series of supramolecular architectures based on Keggin polyoxometalates (POMs): (Hbpy)3[PMo12O40]·2.2H2O (1), (H3/4bppy)4H2[PMo12O40]·3H2O (2), (Hbppy)4H2[SiW12O40]·3H2O (3) and (Hppy)4H2[SiMo12O40] (4) (bpy=4-(5-chloropyridin-2-yl)pyridine, ppy= 4-(5-phenylpyridin-2-yl)pyridine and bppy=4-(5-(4-bromophenyl)pyridin-2-yl)pyridine), has been prepared and characterized. In compound 1, no direct interaction occurs among POM anion clusters, and the anions together with organic molecule bpys construct the supramolecular frameworks to accommodate guest water molecules. In compounds 2 and 3, Keggin anions form one-dimensional pillar-like inorganic chains as a ‘guest’ to occupy the supramolecular spaces formed by compact organic array, while POMs form two-dimensional layers and alternative array with organic layers in compound 4. Noncovalent interactions of hydrogen bonding, aryl packing and halogen bonding coexist in compounds 1-3. The C-X…O (X=Cl or Br) synthon is introduced for the first time to drive self-assembly process of POMs. The crystal structure analyses reveal that the substituted groups of organic bipyridine have a major influence on the packing arrangement of crystals. Additionally, the different cation: anion ratios (3 in 1, and 4 in the other compounds) may also in part affect the packing modes of the organic and inorganic moieties.

A 1D double-chain assembly based on the monosubstituted Keggin polyoxometalate (POM) with pendant ligands and of formula {[Ag2(bppy)3][Ag(bppy)2][Ag(bppy)]2PW11Co(bppy)-O39}·2H2O (1) [bppy = 5-(4-bromophenyl)-2-(4-pyridinyl)pyridine] has been synthesised and characterised. The crystals of 1 belong to the space group P1, Mr = 5801.06, a = 18.720(4) A, b = 19.474(4) A, c = 19.815(4) A, α = 96.30(3), β = 96.07(3), γ = 90.12(3)°, V = 7139(2) A3, Z = 2, Dcalcd. = 2.699 Mg·m-3. The final statistics based on F2 are GOF = 1.007, R1 = 0.0620 and wR2 = 0.1346 for I>2σ(I). X-ray diffraction analysis revealed that the structure of 1 contains a 1D chain constructed from a monosubstituted tungstophosphate with one pendant conjugated ligand, five silver-bppy groups and two water molecules. The periphery of the Keggin cluster consists of five Ag-bppy groups so that a bicapped trisupporting Keggin structure is obtained. It is rare that a Keggin anion cluster is simultaneously coordinated to five transition metal atoms.

An inorganic-organic hybrid polyoxometalate (POM) (Hbpy)4[SiMo12O40] (1) (bpy = 2,4-bipyridine), has been prepared and characterized. X-ray diffraction study reveals that compound 1 contains interesting organic double helical chains. The hybrid nanoparticles was used as a solid bulkmodifier to fabricate a three-dimensional chemically modified carbon paste electrode (1-CPE) by direct mixing. The electrochemical behavior and electrocatalysis of 1-CPE has been studied in detail. The results indicate that 1-CPE has a good electrocatalytic activity toward the reduction of nitrite in 1M H2SO4 aqueous solution. 1-CPE shows remarkable stability that can be ascribed to the interactions existed between POM anions and organic double helical bpy chains, which are very important for practical applications in electrode modification.

The crystal structure of H3PMo6W6O40 3C2H6O was determined by X-ray crystallography and refined to R=0.0698 based on 2279 observed reflections to give unit cell parameters a=16.48(2) (A), c=25.205 (5) A, γ=120°, hexagonal, space group R3. The organic solvent molecules were characterized also by IR, 1H NMR spectra. Weak interaction existed between the organic solvent and the heteropoly acid in the secondary structure. The novel compoundd showed different behaviours in solubility, oxidizability and photosensitivity in comparison with classical dodeca heteropolyacid of molybdenum and tungsten.

Three novel [γ-SiW10O36]8- dimers, [{K(H2O)}2{(μ3-H2O)M-(H2O)}(γ-Si2W20O70)]8- (M = Mn2+, 1; Co2+, 2; Ni2+, 3), are isolated from an aqueous acidic medium without isomerization, which is different from most reactions of [γ-SiW10O36]8- with first-row transition metals. They are isomorphous and crystallize in the orthorhombic system, space group Pnma. These species are the first examples of imidazole-potassium mixed salts of Keggin-γ-type dimers having an analogous open structure related to the Wells-Dawson anionic cluster.

A luminescent multilayer film has been fabricated from mixed-addenda polyoxometalate anion [Eu(SiW4Mo7O39)2]13- (EuSiWMo) and polyethyleneimine (PEI) through electrostatic layer-by-layer self-assembly (LBL). The fabrication processes of the film have been monitored by UV-Vis absorption spectra. The results indicated that the composite film was formed by the alternate adsorption of EuSiWMo and PEI, and the layer growth was linear and highly reproducible from layer-to-layer. The elemental composition of the film was obtained from X-ray photoelectron spectrum (XPS). The data of XPS confirmed the presence of the expected elements. The film was smooth and homogeneous as indicated by atomic force microscopy images (AFM). The close-packed nanoclusters of the conglomeration of EuSiWV anions, with a mean grain size of ca. 60 nm, are distributed on the surface uniformly. The mean interface roughness estimated by AFM is about 3.8 nm in an area of 2:0×2:0 μm2. The film exhibited characteristic emission bands of rare-earth ions, consisting with those of the solid sample. In addition, the electrochemical behavior of the film was investigated by cyclic voltammetry, indicating that the electrochemical property of EuSiWMo was fully maintained in the LBL film.

In this paper we focus on the electrochromic property of a multicolour film containing transition metal ion doped hexagonal tungsten bronze (TM-HTB), Fe0.20-HTB, and Cu0.15-HTB. Compared with the HTB or Mo-HTB films, the colour range of the TM-HTB films was greatly extended, while the switching speed, colour contrast and electrochromic efficiency were almost unchanged. The Fe0.20-HTB film could change colour from orange to blue. Its colour contrast and coloration efficiency are 46.6% and 38.1, respectively. And the Cu0.15-HTB film changes from yellow-green to dark blue under the control of an electric signal. Its colour contrast and coloration efficiency are 38.7% and 54.2, respectively. The switching speed for Fe0.20-HTB and Cu0.15-HTB film is 8 s(reduction)/2 s(oxidation) and 8.5 s(reduction)/2 s(oxidation).

Two novel complexes based on the Keggin POMs modified by the Cu(4,4’-bipy) moiety, {[Cu(4,4’-bipy)]3[HSiMo12O40]}·1.5H2O (1) and {[Cu(4,4’-bipy)]4[SiW12O40]}·3H2O (2) (bipy =bipyridine), have been hydrothermally synthesized and characterized by routine physical methods and single-crystal Xray diffraction. Complexes 1 and 2 represent the first examples of fully oxidized Keggin POM anions as pendant polydentate ligands covalently bonded to a multitrack Cu(bipy) polymer chain(s) through linearly arrayed Od···Oc···Od (Od, terminal oxygen; Oc, bridging oxygen) atoms of singleM3O13 triad(s). In the crystalline lattice of 1, the 1D chain is constructed from a α-[SiMo12O40]4- (SiMo12) cluster as a pendant tridentate ligand covalently bonded to three CuI(4,4’-bipy) subunits, and the neighbouring polymer strands interconnect with the Keggin fragments geared like the teeth of a zipper. In compound 2, the 2D extended layer structure is composed of a α-[SiW12O40]4- (SiW12) cluster as a pendant hexadentate ligand covalently bonded to four CuI(4,4’-bipy) subunits and forms a 2D net-texture structure with a large vacancy (30.9×10.6 Å), and the 2D layers are arranged in a parallel staggering fashion to form a 3D framework.
