Working Paper

Abstract

A dinuclear dysprosocenium dication has been synthesised that is bound together by weak interactions between {Dy(Cp*)₂}⁺ fragments and neutral NEt₃AlMe₃ molecules. The axiality of the Dy³⁺ crystal fields are perturbed by these equatorial interactions but a relatively large effective barrier to magnetisation reversal of 860(60) cm^–1 and magnetic hysteresis up to 15 K are observed.
