The novel title polyvanadate(V), poly[[octa-mu-aqua-dodeca-aqua-mu(4)-octacosaoxidodecavanadato-hexasodium] tetrahydrate], [Na-6(H2O)(20)(V10O28)center dot 4H(2)O](n), contains [V10O28](6-) anions which lie about inversion centres and have approximate 2/m symmetry and which are linked to [Na-3(H2O)(10)](3+) cations through two terminal and two mu(2)-bridging O atoms. The structure contains three inequivalent Na+ cations, two of which form [Na-2(H2O)(8)](n) chains, which are linked via NaO6 octahedra involving the third Na+ ion, thus forming a three-dimensional framework.
