The title compound, Ag0.60Na0.40Fe(MoO4)2 {silver sodium iron(III) bis-[molyb-date(VI)]}, was synthesized by a solid-state reaction. The structure is built up from FeO6 octa-hedra and MoO4 tetra-hedra sharing corners to form a two-dimensional framework parallel to the (001) plane. The occupationally disordered (Ag/Na)(+) cations are located in the inter-layer space. These [Fe(MoO4)2 (-)] n layers are similar to those in the isotypic yavapaiite-related structure of NaFe(MoO4)2. All atoms are on general positions except for Fe (site symmetry -1) and Ag/Na (site symmetry 2). The Ag/Na occupancies of the latter site were refined to 0.597 (4):0.403 (5). The title structure is compared to similar structures.
标题化合物Ag0.60Na0.40Fe(MoO4)2{银钠铁(III)双[钼酸根(VI)]}通过固相反应合成。其结构由FeO6八面体和MoO4四面体共享角形成平行于(001)平面的二维框架。占据无序的(Ag/Na)(+)阳离子位于层间空间。这些[Fe(MoO4)2(-)]n层与NaFe(MoO4)2的同型相关结构中的层相似。除Fe（位点对称性-1）和Ag/Na（位点对称性2）外，所有原子均处于一般位置。后一位点的Ag/Na占有率精修为0.597 (4):0.403 (5)。将标题结构与类似结构进行了比较。
