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.
Two kinds of mixed valencesodium vanadate [FeⅡ2Cl8V10O18 (H2O)] Cl2 · xH2O and [FeⅢ2Cl8V10O18 (H2O)] Cl4 · yH2O containing transition elements Fe Ⅱ and Fe Ⅲ were synthesized and characterized by elemental analysis, IR, TG and ESR The results showed that the V elements of the two title compounds have two valence states VIV and VV, the second transition element Fe still retains the valence state of Fe in the reaction raw material, and is the mixed valence of the transition element Fe State ten vanadate.
