摘要: A pentanuclear dysprosium hydroxy cluster of composition [Dy5(μ4-OH)(μ3-OH)4(μ-η2-Ph2acac)4(η2-Ph2acac)6] (1; Ph2acac = dibenzoylmethanide) was prepared starting from [DyCl3·6H2O] and dibenzoylmethane. Both static (dc) dynamic (ac) magnetic properties 1 have been studied. Below 3 K, the appearance slow relaxation magnetization typical for single-molecule magnets is seen, even if no hysteresis effects on M vs H data are observed above 1.8 K.
