| 中文摘要 | [dy-iii(hbpz(3))(2)](2+) moieties (hbpz(3)(-) = hydrotris(pyrazolyl)borate) and a 3d transition-metal ion (fe-iii or co-iii) have been rationally assembled using an dithiooxalato dianion ligand into 3d-4f [mdy3(hbpz(3))(6)(dto)(3)]center dot 4ch(3)cn center dot 2ch(2)cl(2) (m = fe (1), co (2) complexes. single-crystal x-ray studies reveal that three eight-coordinated dy-iii centers in a square antiprismatic coordination environment are connecting to a central octahedral trivalent fe or co ion forming a propeller-type complex. the dynamics of the magnetization in the two isostructural compounds, modulated by the nature of the central m-iii metal ion, are remarkably different despite their analogous direct current (dc) magnetic properties. the slow relaxation of the magnetization observed for 2 mainly originates from isolated dy ions, since a diamagnetic co-iii metal ion links the magnetic dy-iii ions. in the case of 1, the magnetic interaction between s = 1/2 fe-iii ion and the three dy-iii magnetic centers, although weak, generates a complex energy spectrum of magnetic states with low-lying excited states that induce a smaller energy gap than for 2 and thus a faster relaxation of the magnetization. |
