Synthesis Structures And Properties Of Some Transition Metal-modified Polyoxometalates

Recently, the design and synthesis of organic-inorganic hybrid compounds based on polyoxometalate blocks are of great interest owing to not only their intriguing structural frameworks but also potential applications in catalysis, medicine and materials etc.In this thesis, seven organic-inorganic hybrid compounds have been synthesized on the basis of hydrothermal technique and and structurally characterized by elemental analyses, IR and single crystal X-ray diffractions. The thermal stabilities, fluorescent properties, electrochemical behavior of a part of the compounds have been studied.Seven new organic-inorganic hybrid compounds (1～7) have been synthesized based on based on hydrothermal technique by the introductin of {MxLy}(M= transiton metal ions, L= N-donor ligands) fragments and structurally characterized: [ZnⅡ(C10H8N2)2(H2O)2][SiW12O40]·5H2O(1) [NiⅡ(C10H8N2)(C2H8N2)2]2[ClWⅤ1WⅥ11O40]·5H2O(2) {[AgⅠ(4,4'-bipy)]3[PW12O40]}-(4,4'-bipy)·4H2O(3) {[Ni(C10H8N2)3]2(O26MoⅥ8)}-6H2O(4) {[CuⅠ(C12H8N2)2]4[(CuⅠ5O4)(C12H8N2)4][H4BⅢWⅥ12O40]}·6H2O(5) [CuⅠ(C4H10N2)2]{[CuⅠ(C4H10N2)2](CuⅠ2O2)(H12VⅣ5MoⅥ8O40)}·(C4H10N2)·4H2O(6) [NaⅠ(C10H8N2)(HO22MoⅥ7)](7)...
