The reaction between PW9O349- and NpO2+ has yielded the first structurally characterized neptunyl(V) polyoxometalate complex, [Na2(NpO2)2(A-PW9O34)2]14-. This complex is isostructural with the uranyl(VI) analogue, and there is also spectroscopic evidence for its existence in solution. The complex is readily extracted into toluene, and this may have significance in the sequestering and/or separation of the neptunyl ion in terms of nuclear waste management.
PW9O349- 与 NpO2+ 之间的反应生成了首个结构表征明确的镎酰（V）多金属氧酸盐配合物 [Na2(NpO2)2(α-PW9O34)2]14-。该配合物与铀酰（VI）类似物同构，并且也有其在溶液中存在的光谱证据。该配合物很容易被萃取到甲苯中，这在核废料管理方面对镎酰离子的螯合和/或分离可能具有重要意义。
