共配体策略构筑的七核镝簇合物的合成及其磁学性能
Synthesis and magnetic properties of dysprosium heptanuclear cluster compound constructed by co-ligands strategy
摘要
Abstract
A dysprosium heptanuclear cluster[Dy7(H2O)3(μ3-OH)4(3-NBA)9(L)4]was prepared by solvothermal using 2-hy-droxy-5-methoxy-N'-(pyridin-2-methylene)-benzoyl hydrazide(H2L)and m-nitrobenzoic acid(m-NBA)as co-ligands.The structure and magnetic properties of the complex were characterized by single-crystal and powder X-ray diffraction,elemental analysis,FT-IR spectrum,thermogravimetric analysis,direct current and alternating current magnetic susceptibility testing.Theresults showed that:① The complex crystallized in the triclinic Pl space group with a=1.647 29(6)nm,b=1.957 98(7)nm,c=2.436 18(9)nm,α=80.354(3)°,β=84.511(3)°,y=69.422(3)°,V=7.246 4(5)nm3 and Z=2.② The complex featured a butterfly-shaped heptanuclear cluster aggregated by hydroxyl groups.③ The complex exhibited antiferromagnetic interactions and did not exhibit frequency dependent behavior in both zero and applied fields,indicating the presence of strong quantum tunneling effects within the complex molecules.关键词
