Isolation of extendable transition metal incorporated polyoxometalate intermediates with structural control†
Abstract
Three discrete cobalt-substituted silicotungstates, [Co3(H2O)(B-β-SiW9O34)(B-β-SiW8O29(OH)2)]12− (1), [Co3(H2O)(B-α-SiW9O34)(B-β-SiW8O31)]14− (2), and [Co9Cl2(OH)3(H2O)9(B-β-SiW8O31)3]17− (3), have been synthesized using a synthetic approach involving Co(II) ions, the dilacunary [γ-SiW10O36]8−polyanion and a bulky organic
