| 摘要: 用粉状白钨酸作原针,在一般条件下制备K3W2Cl9,产率达53%,证明白钨酸是比黄钨酸优越的钨化学试剂。研究了K3W2Cl9经离子又换转化为酸的形态后与Ndz2(C03)3的反应。得到了新的化合物NdW2Cl9,提出了一条新的制备溶解度大的各种金属离子与W2Cl93-的化合物的途径。
对K3W2Cl9和NdW2Cl9进行了紫外可见尤谱和X针线粉末衍射的测定。 |

| Abstract: Using powdery white tungstic acid as raw material,K3W2Cl9 has been prepared under ordinary conditions with 53% yield confirming that white tungstic acid as a chemical reagent of tungsten is superior to the yellow species. By the use of H-form cation exchanger,K3W2Cl9 is readily converted to the corresponding acid which reacts with Nd2(CO3)3 giving NdW2Cl9. This is a general method for the preparation of metal salts of enneachloroditung-state.Visible and UV spectra and X-ray powder diffraction of K3W2Cl9 and NdW2Cl9 have been determined. |
