摘要：

The first triradical bridged binuclear penta-spin single-molecule magnet, [Dy-2(hfac)(6)(BTR)], based on a nitronyl nitroxide triradical was synthesized and characterized. Theoretical calculations revealed Dy-radical anti-ferromagnetic coupling and radical-radical ferromagnetic coupling. The SMM behavior is found to originate from the exchange states, rather than the isolated Dy3+ center.
