标题化合物的结构是由氧化钒层组成的，层之间插有NH4+阳离子。每一对VO5方形金字塔都由一个边缘桥接，形成一个双V2O8组。V2O8组通过共享角连接在一起，形成扭曲的之字形链。每个VO6八面体通过两条边与两个V2O8基团连接，通过两个角与另外两个V2O8基团连接，这样，通过VO6八面体通过共享角和边将扭曲的之字形链连接在一起，形成层状结构。有N-H…氧化钒层和NH4+阳离子之间的氢键。
The structure of the title compound is made up of vanadium oxide layers, with NH4+ cations intercalated between the layers. Each pair of VO5 square pyramids is bridged by an edge to form a double V2O8 group. The V2O8 groups are connected by sharing corners to produce a twisted zigzag chain. Each VO6 octahedron is connected to two V2O8 groups by two edges and to another two V2O8 groups by two corners, Hence, the twisted zigzag chains are held together through VO6 octahedra by sharing corners and edges to form a layer structure. There are N-H ... O hydrogen bonds between the vanadium oxide layer and the NH4+ cations.
