用光合成的方法得到了两个混合价的缺位磷钨杂多化合物，其缺位分别位于“带”和“帽”的位置．这两个混合价的杂多化合物仍然保持了其母体化合物Dawson的结构类型．在这两个混合价杂多化合物中，由于缺位位置不同造成的“蓝电子”离域情况的变化，导致了其在磁性质上的差异．
Two mixed valence HgP heteropoly compounds were obtained by photo-synthesis method, and their vacancies were located at “band” and “cap” respectively. Heteropoly compounds of these two mixed valences still maintain the structural type Dawson of their parent compound. In these two mixed-valence heteropoly compounds, the change of “blue-electron” delocalization due to the absence of vacancy sites leads to their difference in magnetic properties.
