| 中文摘要 | the reaction of dy(no(3))(3)center dot 6h(2)o with the ligand 2-((1-hydroxybutan-2-ylimino)methyl) phenol (h(2)l, scheme 1) generates the nonanuclear compound [dy(9)l(8)(mu(3)-oh)(8)(mu(4)-oh)(2)(ch(3)oh)(8)](oh)(ch(3)oh)(3) (dy(9)), whose single-crystal x-ray structure reveals the presence of two square pyramidal pentanuclear units assembled via the apical metal center. the square pyramidal core of a previously reported [dy(5)(mu(4)-oh)(mu(3)-oh)(4)(mu-eta(2)-ph(2)acac)(4)(eta(2)-ph(2)acac)(6)] (dy(5); ph(2)acac = dibenzoylmethanide), is structurally related to those herein described; however, the magnetic properties of dy(9) and dy(5) are drastically different. indeed, dy5 shows slow relaxation of magnetization while no out-of-phase ac signal is noticed for dy(9). the underlying mechanism is not clear due to the complexity of such systems; however, the different anisotropy of the respective structures, which is dictated by the combination of the metal topology, the ligands involved and the structural parameters of the molecule, is mostly responsible for the distinctive relaxation dynamics observed. |
