Switching slow relaxation in a MnIII3MnIV cluster: an example of grafting single-molecule magnets onto polyoxometalates

Abstract

Binding an established single-molecule magnet cluster of distorted cubane type [Mn(III)(3)Mn(IV)O(4)] to the lacunary site of an {alpha-P(2)W(15)} polyoxotungstate scaffold results in a surprising zero-field splitting inversion and the subsequent loss of magnetization bistability.
