The structure of NaLaIII(SO4)2.H2O consists of distorted Na-O6 octahedra, La-O9 complexes in the form of distorted tricapped trigonal prisms, and slightly irregular tetrahedral sulfate ions. All bond distances fall within normal limits. The sulfate ions manifest rigid-body behavior but this is not the case for either of the cation complexes. The single water molecule is modelled as having O-atom disorder but an ordered H atom. Hydrogen bonds involve only sulfate O atoms as acceptors. The absolute structure has been determined.
NaLaIII(SO4)2·H2O的结构由扭曲的Na-O6八面体、呈扭曲三帽三棱柱形式的La-O9络合物以及略微不规则的四面体硫酸根离子组成。所有键长均在正常范围内。硫酸根离子表现出刚体行为，但阳离子络合物并非如此。单个水分子被建模为具有O原子无序但H原子有序的结构。氢键仅涉及硫酸根O原子作为受体。绝对结构已确定。
