摘要
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 lacunary tungstodiphosphates with the lacuna located in 'belt' and 'cap' posi-tions were photosynthesized. These mixed-valence species retains the Dawson structure. The 'blue' electron delocalized over the belt W atoms in lacunary species was analogous to that of the perfect species. It was found that a1-[P2W17O61]11- was more paramagnetic than a2-[P2W17O61]11-, due to the fact that the lacuna in 'belt' po-sition did not transmit the circulating 'blue' electron well and blocked the ring current somewhat, thus reduced the effectiveness of its ring current in diminishing paramagnetism.
