Abstract

We report a dichlorido-bridged dinuclear dysprosium(iii) single-molecule magnet [Dy(Cy₂N)₂(μ-Cl)(THF)]₂ which shows an effective energy barrier for magnetization reversal (U_eff) of ca. 623 K. This is by far the largest U_eff barrier for any chlorido-bridged lanthanide single-molecule magnet. We observe two relaxation processes with near-identical temperature dependencies, one of which disappears upon magnetic dilution. We suspect that these two processes are the isolated and coupled relaxation processes.
