本文用X射线散射技术和~（35）Cl核磁共振谱研究了金属高氯酸盐溶液。这项工作的目的是获得铈和高氯酸盐基团之间的络合物形成和ClO-4 - H2O相互作用的结构信息。的NMR数据，相关函数和结构功能的分析同意文献信息的Ce -（OClO 3）z物种存在于水溶液中。与实验数据的良好协议是通过一个模型，其中高氯酸根离子键合作为单齿配体的铈（III）。Mg（II）没有络合物形成。阳离子还具有水分子的第二配位壳层。已经获得了一些支持ClO-4 - H2O接触存在的迹象。
Metal-perchlorate solutions have been investigated by the X-ray scattering technique and 35Cl NMR spectroscopy. The aim of this work was to obtain structural information on the complex formation between the Cerium and the Perchlorate group and on the ClO-4 - H2O interactions. The NMR data, the correlation functions and the analysis of the structure functions agree with the literature information about the Ce - (OClO3)z species present in aqueous solutions. Good agreement with experimental data is achieved through a model in which the Perchlorate ions are bonded as monodentate ligands to the Cerium(III). No complex formation is confirmed for Mg(II). The cations also possess a second coordination shell of water molecules. Some indications have been obtained supporting the presence of ClO-4 - H2O contacts.
