A Trigonal-Pyramidal Erbium(III) Single-Molecule Magnet. Academic Article uri icon


  • Given the recent advent of mononuclear single-molecule magnets (SMMs), a rational approach based on lanthanides with axially elongated f-electron charge cloud (prolate) has only recently received attention. We report herein a new SMM, [Li(THF)4[Er{N(SiMe3)2}3Cl]2THF, which exhibits slow relaxation of the magnetization under zero dc field with an effective barrier to the reversal of magnetization (Eeff/kB =63.3K) and magnetic hysteresis up to 3K at a magnetic field sweep rate of 34.6Oes(-1). This work questions the theory that oblate or prolate lanthanides must be stabilized with the appropriate ligand framework in order for SMM behavior to be favored.
