摘要 制备了铕 (Ⅲ )的二茂铁单甲酸基双核配合物 [Eu2 ( μ2 - η2 -OOCFc) 2 (OOCFc) 4 (H2 O) 4 ]·2MeOH·H2 O ,式中 :Fc =( η5-C5H5)Fe( η5-C5H4)。采用单晶X -衍射、元素分析、红外光谱等方法对其进行了结构表征 ,进而采用变温磁化率法测试了该化合物在 5 .0~ 3 0 0K范围内的磁效应 ,结果显示 。 Ferrocenecarboxylato-bridged Eu(Ⅲ) dimer [Eu_2(μ_2-η~2-OOCFc)_2(OOCFc)_4(H_2O)_4]·2MeOH·H_2O,Fc=(η~5-C_5H_5)Fe(η~5-C_5H_4), is prepared according to literature method. Its structure is characterized by elemental analysis, IR and single X ray crystallography. Moreover, its magnetic properties are studied at the temperature range of 5.0~300 K. The results show that, the dimer exhibits very strong paramagnetic interactions.
