The novel title polyvanadate(V) contains [V10O28]6− anions which lie about inversion centres and have approximate 2/m symmetry and which are linked to [Na3(H2O)10]3+ cations through two terminal and two μ2-bridging O atoms. The structure contains three inequivalent Na+ cations, two of which form [Na2(H2O)8]n chains, which are linked via NaO6 octahedra involving the third Na+ ion, thus forming a three-dimensional framework.
