摘要：
The pentalene-ligated dysprosium complex [((8)-Pn(dagger))Dy(Cp*)] (1(Dy)) (Pn(dagger) = [1,4-((Pr3Si)-Pr-i)(2)C8H4](2-)) and its magnetically dilute analogue are single-molecule magnets, with energy barriers of 245 cm(-1). Whilst the [Cp*](-) ligand in 1(Dy) provides a strong axial crystal field, the overall axiality of this system is attenuated by the unusual folded structure of the [Pn(dagger)](2-) ligand.
