| 中文摘要 | self-assembly of polydentate schiff base 2,6-diformyl-4-methylphenol di(benzoylhydrazone) (h3l), with dysprosium thiocyanate and sodium azide, affords two novel trinuclear triangular circular helicate dysprosium(iii) complexes, [dy-3(mu(3)-och3)(2)(hl)(3)(scn)]center dot 4ch(3)oh center dot 2ch(3)cn center dot 2h(2)o (1) or [dy-3(mu(3)-n-3)(mu(3)-oh)(h2l)(3)(scn)(3)](scn)center dot 3ch(3)oh center dot h2o (2), depending on the presence or absence of base. single-crystal x-ray analyses show that two mu(3)-methoxy oxygens cap the dy-3 triangle in complex 1 and that one mu(3)-oh and one mu(3)-n-3(-) cap the dy-3 triangle of complex 2, representing the first example of a mu(3)-n-3(-)-capped lanthanide complex reported to date. ac susceptibility measurements reveal that multiple relaxation processes and the onset of slow magnetization relaxation occur for complex 1 and 2, respectively. theoretical calculations are required to elucidate the underlying mechanism; however, the different magnetic anisotropy of the respective structures, which is dictated by the coordination environment of dy-iii ions and structural parameters of the triangles, is mostly responsible for the distinctive relaxation dynamics observed. |
