A double-dysprosocenium single-molecule magnet bound together with neutral ligands

A dinuclear dysprosocenium dication has been synthesised that is bound together by weak interactions between {Dy(Cp∗) } fragments and neutral NEt AlMe molecules. The axiality of the Dy crystal fields are perturbed by these equatorial interactions but a relatively large effective barrier to magnetisation reversal of 860(60) cm and magnetic hysteresis up to 12 K are observed. 2 3 3 + 3+ -1
