资源简介：
A synthetic protocol
was developed that involves the transmetalation
of a mono-dysprosium–[1]ferrocenophane complex with DyX3 (X = Cl– or I–) to afford
[Dy3Fc6Li2(THF)2]−, featuring a rare linear arrangement of magnetically
anisotropic Dy3+ ions. The close spatial inter-lanthanide
proximity, in combination with μ2-bridging sp2-hybridized CCp groups, enforces significant magnetic
coupling and results in hard single-molecule magnet (SMM) behavior,
with an effective barrier to magnetization reversal of up to 268 cm–1. Our results highlight the versatility of lanthanide
metallocenophane architectures toward the development of novel
multinuclear SMM frameworks.
