The novel title polyvanadate(V), poly[[octa-mu-aqua-dodecaaqua-mu(4)-octacosaoxidodecavanadato-hexasodium] tetrahydrate], Na(6)(H(2)O)(20)(V(10)O(28)).4H(2)O, contains V(10)O(28) anions which lie about inversion centres and have approximate 2/m symmetry and which are linked to Na(3)(H(2)O)(10) cations through two terminal and two mu(2)-bridging O atoms. The structure contains three inequivalent Na(+) cations, two of which form Na(2)(H(2)O)(8) chains, which are linked via NaO(6) octahedra involving the third Na(+) ion, thus forming a three-dimensional framework.
新型标题多钒酸盐（V），聚[[八-μ-水合十二水合-μ(4)-二十八氧化十钒酸六钠]四水合物]，Na(6)(H(2)O)(20)(V(10)O(28)).4H(2)O，包含位于反演中心且具有近似2/m对称性的V(10)O(28)阴离子，这些阴离子通过两个端基和两个μ(2)-桥连O原子与Na(3)(H(2)O)(10)阳离子相连。该结构包含三个不等价的Na(+)阳离子，其中两个形成Na(2)(H(2)O)(8)链，这些链通过涉及第三个Na(+)离子的NaO(6)八面体相连，从而形成三维框架。
