标题化合物八硫酸二铈八铵四水合物的晶体，适合于X射线工作，通过水热反应制备。该结构由[Ce 2（SO 4）8]8−阴离子组成，通过氢键与结晶沃茨和NH 4+阳离子相互作用。[Ce 2（SO 4）8]8−阴离子中的铈（IV）与属于硫酸根基团的O原子配位九次。配位多面体是一个有点扭曲的三帽三棱柱。Ce-O距离在2.325（2）-2.478（2）μ m之间。
Crystals of the title compound, octaammonium dicerium octasulfate tetrahydrate, suitable for X-ray work, were prepared by a hydrothermal reaction. The structure is made up of [Ce2(SO4)8]8− anions, interacting with the crystallization waters and the NH4+ cations through hydrogen bonds. Cerium(IV) in the [Ce2(SO4)8]8− anion is ninefold coordinated by O atoms belonging to sulfate groups. The coordination polyhedron is a somewhat distorted tricapped trigonal prism. The Ce—O distances range from 2.325 (2) to 2.478 (2) Å.
