Organic-soluble lacunary {M2(P2W15)2} polyoxometalate sandwiches showing a previously unseen αββα isomerism

Author affiliations

Abstract

New polyoxometalate ‘sandwiches’ have been formed where two [P2W15O56]12− lacunary Dawson clusters encapsulate two transition metal ions to give clusters with the general formula [MII2(P2W15O56)2]20− (where M = Mn, Co, and Ni respectively), [FeIII2(P2W15O56)2]18−, and [CuII4(P2W15O56)2]16−. The Mn, Co, and Ni clusters exhibit a hitherto unseen αββα isomeric geometry and all five compounds are associated with tetrabutylammonium cations which allow for their dissolution in non-aqueous solvent.
