A Double-Dysprosocenium Single-Molecule Magnet Bound Together with Neutral Ligands

preprint
submitted on 15.11.2019 and posted on 25.11.2019 by Peter Evans, Daniel Reta, Conrad Goodwin, Fabrizio Ortu, Nicholas Chilton, David Mills
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.
