英文摘要 | a family of four dy-3 triangular circular helicates, namely, [dy-3(hl)(3)(mu(3)-oh)(ch3oh)(2)(h2o)(4)]cl-1.5(oh)(0.5).0.5h(2)o (1), [dy-3(hl)(3)(mu(3)-oh)(ch3oh)(3)(h2o)(2)cl]cl.ch3oh (2), [dy-3(hl)(3)(mu(3)-oh)(ch3oh)(3)(h2o)(2)(no3)](no3) (3), and [dy-3(hl)(3)(mu(3)-oh)(ch3oh)(4)(clo4)](clo4) (4), were assembled by the reaction of a new acylhydrazone ligand h3l [(3-hydroxy)-n'-((8-hydroxyquinolin-2-yl)methylene)picolinohydrazide] with different dysprosium(iii) salts. these compounds represent the first examples of mu-oacylhydrazone-bridged triangular dy3 smms reported to date. alternating-current magnetic susceptibility measurements revealed that compounds 1 and 2 show typical smm behavior with the occurrence of multiple relaxation processes, whereas frequency-dependent relaxation signals without chi peaks were observed in 3 and 4 under zero dc field. such distinct dynamic behaviors are attributed to the different sizes of the terminal coordination solvent/anions (h2o, cl, no3, and clo4 for 1-4, respectively) at the dy-3 site. here, similar deviations from the ideal monocapped square-antiprismatic (c-4v) geometry defined by shape software were observed around local dy centers in 1 and 2, whereas the situation was completely different in 3 and 4 as a result of the presence of relatively large anions in the limited space defined by three intercrossing rigid hydrazone ligands. |
