The title compound, sodium dioxidomolybdenum(VI) arsenate(V), β-NaMoO(2)AsO(4), was prepared by solid-state reaction at 953 K. In the crystal structure, the AsO(4) tetra-hedra and MoO(6) octa-hedra (both with m symmetry) share corner atoms to form a three-dimensional framework that delimits cavities parallel to [010] where disordered six-coordinated sodium cations (half-occupation) are located. Structural relationships between the different orthoarsenates of the AMoO(2)AsO(4) series (A = Ag, Li, Na, K and Rb) are discussed.
标题化合物砷酸（Ⅴ）二氧钼（Ⅵ）钠，β-NaMoO₂AsO₄，通过在953 K下的固态反应制备。在晶体结构中，AsO₄四面体和MoO₆八面体（均具有m对称性）共享角原子以形成三维框架，该框架界定了平行于[010]的空腔，无序的六配位钠阳离子（占据率为一半）位于其中。讨论了AMoO₂AsO₄系列（A = Ag、Li、Na、K和Rb）中不同原砷酸盐之间的结构关系。
