Dysprosium-based single-molecule magnets: Single-molecule magnets (SMMs) of dinuclear dysprosium(III) having thermal and quantum tunneling regimes of magnetization relaxation have been synthesized. Remarkably large energy barriers up to 71 K are observed, in particular for the polymeric complex network, which has the largest energy gap for a lanthanide complex and one of the highest barriers reported for a SMM.
