| 中文摘要 | a series of mixed-valent heterometallic pentanuclear (co3coreiii)-co-iii-r-ii (re = gd (1), tb (2), y (3)) clusters have been rationally assembled by taking advantage of a bifunctional ligand with o-vanillin and tripodal tris(hydroxymethyl) aminomethane units. structural determinations reveal that all compounds are isomorphous and possess a t-shaped co4re core, which comprises two nearly linear co2re subunits sharing a common re ion. their magnetic properties were thoroughly studied. the static magnetic susceptibility studies of 1 demonstrate the presence of weak ferromagnetic interactions between the magnetic centres and magnetic anisotropy reflected by the single ion zero-field splitting (zfs) d term. both 1 and 2 behave magnetically as heterodinuclear metal systems, while the magnetic behaviour of 3 is identical to an isolated co-ii ion. moreover, alternating-current susceptibility measurements did not exhibit any out-of-phase signal, suggesting that slow magnetic relaxation is absent above 2 k within them. these isomorphous co4re clusters offer an opportunity to systematically probe the contribution of different metal ions to the overall magnetic behaviour in co-ii-reiii systems. |
