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*) 2 } + fragments and neutral NEt 3 AlMe 3 molecules. The axiality of the Dy 3+ crystal fields are perturbed by these equatorial interactions but a relatively large effective barrier t...

Description
Summary:A dinuclear dysprosocenium dication has been synthesised that is bound together by weak interactions between {Dy(Cp*) 2 } + fragments and neutral NEt 3 AlMe 3 molecules. The axiality of the Dy 3+ 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 12 K are observed. Double dysprosocenium: we report a dinuclear complex containing two dysprosocenium cations, unusually held together by electrostatic interactions with neutral molecules.
