摘要
采用直接合成法成功地合成了1∶11双系列镧系元素钼砷杂多化合物Na11〔LnAsMo11O39〕2〕xH2O(Ln=La,Ce,Pr,Pr,Sm)。用极谱、红外、元素分析和X-射线衍射等方法对其组成和结构进行了研究。结果表明,合成的稀土杂多化合物结构相同,但Ln取代Mo-Od后对杂多阴离子内部的化学键有一定影响。Ln(AsMo11O39)11-2的氧化还原性质与AsMo12O3-40相比发生了一定变化。
Heteropoly Mo-As complexes of lanthanide elements were directly synthesized. Polar spectrum, X-ray diffraction (XRD), infrared spectroscopy (IR), and elemental analysis were used to research the composition and structure of the products. The results showed that they had the same structure, and Ln had influence on chemcal bond and the character of oxidation-reduction.
