| This dissertation is composed of four parts as following:Part one: review. In this part, the history, structure, classification and future opportunities of heteropoly compounds were reviewed and the research state of heteropoly compounds containing theⅥA elements Te as heteroatom was summarized.Part two: Synthesis and Characterization a series of Heteropolymolybdate with Te6+ containing Lanthanide. In this part, two compounds of heteropolymolybdate with Te6+ containing lanthanide were synthesized and reported for the first time. The physical and chemical properties of these new heteropoly compounds were studied by using chemical analysis, inductively coupled plasma (ICP) atomic emission spectra, infrared spectra, and UV-vis spetra.Part three: Organic-Inorganic hybrid: H2Na2(C6H6AsNO5)2[CoW6O24H6]·2H2O was prepared. The physical and chemical properties of this new heteropoly compound was studied by using elementary analysis, chemical analysis, ICP, IR, UV and XRD.Part four: Synthesis and Characterization of Na6[TeCoW8O30(OH)2]·28H2O and Na6[TeNiW8O30(OH)2]·28H2O. In this part, the title compounds were reported for the first time. The physical and chemical properties of these new heteropoly compouds were studied by using chemical analysis, ICP, IR, UV and XRD.
