【摘要】 本论文由以下四部分组成：第一部分：前言介绍了杂多化合物的基本概念、发展历史、基本结构、分类及将来的发展方向，并对含Te杂多化合物的研究现状进行了文献总结。第二部分：碲钼杂多化合物Ln₂[TeMo₆O₂₄]·20H₂O的合成与表征本文首次合成了含有Eu和Tb碲钼杂多化合物Ln₂[YeMo₆O₂₄]·6H₂O（Ln=Eu，Tb）。用化学分析、UV、IR、XRD等方法对其进行了表征。第三部分：H₂Na₂（C₆H₆AsNO₅）₂[CoW₆O₂₄H₆]·2H₂O的合成与表征本文首次合成了一种特殊的、含有Anderson-Evan结构的无机-有机杂化物H₂Na₂（C₆H₆AsNO₅）₂[CoW₆O₂₄H₆]·2H₂O，通过化学分析、元素分析、IR、UV、XRD等方法对其进行了表征。第四部分：Na₆[TeCoW₈O₃₀（OH）₂]·28H₂O和Na₆[TeNiW₈O₃₀（OH）₂]·28H₂O的合成与表征本文首次合成出了Te取代的Co和Ni的杂多阴离子[TeCoW₈O₃₀（OH）₂]^6-和[TeNiW₈O₃₀（OH）₂]^6-，并以Na盐的形式分离出来，阳离子交换表明Ni和Co处于内界。用化学分析、IR、UV、XRD等方法对其进行了表征。更多还原

【Abstract】 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 theⅥ_A 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.更多还原
