【摘要】 合成了两种分别含有过渡元素FeⅡ和FeⅢ的混合价态十钒酸盐[FeⅡ2Cl8V10O18(H2O)]Cl2·xH2O和[FeⅢ2Cl8V10O18(H2O)]Cl4·yH2O,用元素分析、IR、TG和ESR等方法对其进行了结构表征.结果表明,两种标题化合物中的V元素有VⅣ和VⅤ两种价态,第二过渡元素Fe仍保持反应原料中Fe的价态,为含有过渡元素Fe的混合价态十钒酸盐.更多还原

【Abstract】 Two mixed valent decavanadatesCl₂·xH₂O and 8VCl₄·yH₂O with novel 3-D structure were synthesized and characterized by the methods of elementary analyses,IR,TG and ESR.The results of characterization show that the two title compounds are mixed valent with V^Ⅳand V^Ⅴ,and that the second transition metal Fe still has the same valence in each title compound as it does in the reactants.更多还原
