关于水合锕系离子配位壳及其动力学的基本知识对于这些离子在水溶液中水解、络合和氧化还原反应的热力学描述是重要的这些信息对于预测锕系元素在核储存库的水系统中的迁移以及设计用于分离三价锕系元素（Am3+和Cm3+）和镧系元素（Ln）离子进行分配和嬗变（P&T）的选择性萃取剂是必要的。[1b]然而，由于较轻的锕系元素的氧化还原不稳定性和较重的锕系元素的半衰期很短，对AnIII化合物的结构研究很少在某种程度上，缺乏An3+离子的结构和热力学数据可以用具有类似离子半径的Ln3+离子的数据来弥补。[1a]
Basic knowledge about the coordination shell of hydrated actinide (An) ions and their dynamics is important for a sound thermodynamic description of the hydrolysis, complexation, and redox reactions of these ions in aqueous solution.[1] This information is necessary, for example, for the prediction of actinide migration in the aqueous systems of a nuclear repository and for the design of selective extraction agents for the separation of trivalent actinide (Am3+ and Cm3+) and lanthanide (Ln) ions for partitioning and transmutation (P&T).[1b] However, owing to the redox instability of the lighter actinides and the very short half-lives of the heavier actinides, structural studies of AnIII compounds are rare.[2] The lack of structural and thermodynamic data for An3+ ions can, to some extent, be bridged with data for Ln3+ ions with similar ionic radii.[1a]
