Abstract

We report the first near-linear bis(amide) 4f-block compound and show that this novel structure, if implemented with dysprosium(III), would have unprecedented single molecule magnet (SMM) properties with an energy barrier, Ueff, for reorientation of magnetization of 1800 cm(-1).

Highlights

  • The first near-linear bis(amide) f-block complex: a blueprint for a high temperature single molecule magnet†

  • We report the first near-linear bis(amide) 4f-block compound and show that this novel structure, if implemented with dysprosium(III), would have unprecedented single molecule magnet (SMM) properties with an energy barrier, Ueff, for reorientation of magnetization of 1800 cmÀ1

  • A major breakthrough in the field[3] occurred in 2003 with the observation of SMM behavior in a monometallic {TbPc2}À complex with an energy barrier, Ueff = 230 cmÀ1.4 The ensuing decade saw rapid growth in lanthanide SMMs5 with the Ueff barrier to magnetization reversal increased to 652 cmÀ1 for another derivative of {TbPc2},6 and 585 cmÀ1 for a polymetallic Dy@{Y4K2} complex.[7]
