| 摘要: 用溶剂热方法合成了2个新的3d-4f异金属四核簇合物：[Zn2Ln2（salen）2（CO2PyCH2O）2（MeOH）2]（ClO4）2·2MeOH（Ln=Dy（1），Tb（2）；H2salen=N，N'-双（3-甲氧基水杨基）-1，3-二氨基丙烷；HCO2PyCH2OH=6-羧基吡啶-2-甲醇）。它们是由锌（Ⅱ）Schiff碱构筑模块和6-羧基吡啶-2-甲醇辅助配体组装而成的Zn-Ln2-Zn型簇合物。磁性测量表明稀土离子间存在铁磁性相互作用。Zn2Dy2配合物1在2 000 Oe直流磁场下显示出磁弛豫行为；而Zn2Tb2配合物2不但有磁场导致的磁弛豫行为，而且还具有荧光性质。 |

| Abstract: Two new 3d-4f tetranuclear cluster complexes, [Zn2Ln2(salen)2(CO2PyCH2O)2(MeOH)2](ClO4)2·2MeOH (Ln=Dy (1), Tb (2); H2salen=N,N'-bis(3-methoxysalicylidene)-1,3-diaminopropane; HCO2PyCH2OH=6-(hydroxymethyl)pyridine-2-carboxylic acid), have been prepared solvothermally using Zn(salen) as the building block and CO2PyCH2O2- as the co-ligand. They are Zn-Ln2-Zn cluster complexes. Magnetic measurements indicate ferro-magnetic interactions between lanthanide(Ⅲ) ions. The Zn2Dy2 complex 1 shows magnet relaxation under a 2 000 Oe dc field, while the Zn2Tb2 complex 2 displays both field-induced magnet relaxation and fluorescence properties. |
