We have identified a polydentate aminocarboxylate ligand that stabilizes uranyl(V) in water. The mononuclear [UO2(dpaea)]X, (dpaeaH2 = Bis(pyridyl-6-methyl-2-carboxylate)-ethylamine; X = CoCp2*+ or X = K(2.2.2.cryptand) complexes have been isolated from anaerobic organic solution, crystallographically and spectroscopically characterized both in water and organic solution. These complexes disproportionate at pH ≤ 6, but are stable in anaerobic water at pH 7-10 for several days.

水稳定铀 (V) 配合物的合成和表征。
我们已经确定了一种多齿氨基羧酸配体，它可以稳定水中的铀酰 (V)。单核 [UO2(dpaea)]X, (dpaeaH2 = Bis(pyridyl-6-methyl-2-carboxylate)-乙胺；X = CoCp2*+ 或 X = K(2.2.2.cryptand) 复合物已从厌氧有机溶液，在水和有机溶液中的晶体学和光谱学表征。这些配合物在 pH ≤ 6 时不成比例，但在 pH 7-10 的厌氧水中稳定数天。
