Na₆(H₂O)₂₀(V₁₀O₂₈)·4H₂O, a novel polyvanadate(V) with a three-dimensional framework

H.-X. Guo and Z.-L. Yao

Synopsis: 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 ₂-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.

Formula: Na₆(H₂O)₂₀(V₁₀O₂₈)·4H₂O
