Three ring-shaped Zr(iv)-substituted silicotungstates: syntheses, structures and their properties

Three ring-shaped Zr(iv)-substituted silicotungstates built by the different cluster units of {α-/β-SiW₁₀}/{Zr₂}, {β-SiW₁₀}/{Zr₂}/{Zr₂B}, and {β-SiW₁₀}/{Zr₂B}/{Zr₂B₂} respectively, been made and their related properties have been investigated.
