Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
A mononuclear Er-III sandwich type complex, [Li(DME)(3)][Er-III(COT'')(2)], was isolated using 1,4-bis(trimethylsilyl) cyclooctatetraenyl dianion (COT''). Remarkably, this low-symmetry complex exhibits magnet-like behavior of magnetic remanence and coercivity in the hysteresis loops up to 8 K with an energy barrier (U-eff) of 187(1) K, thus making this molecule a unique single-ion magnet.
