Abstract

Two cyclic cobalt-substituted heteropolyoxometalates K₁₅Li₅[Co₁₀(H₂O)₃₄(P₈W₄₈O₁₈₄)]·54H₂O (1) and K₈Li₁₂[Co₁₀(H₂O)₄₄(P₈W₄₈O₁₈₄)]·60H₂O (2) have been synthesised from the reaction of Co(II) ions and the superlacunary {P₈W₄₈} polyanion in mildly acidic aqueous media. The cluster's anion cavities are filled with Co(II) and K cations and careful manipulation of reaction conditions determines the formation of distinct Co-linked frameworks.
