| 摘 要： | 本文合成了二个双核钴（Ⅱ）配合物，即Ｃｏ２ＬＢｒ３·ＣＨ３ＣＨ２ＯＨ（１）和Ｃｏ２Ｌ（ＳＣＮ）３·ＣＨ３ＣＨ２ＯＨ（２）〔这里ＨＬ是由１，３－二氨基－２－丙醇与Ｎ－氧化吡啶－２－甲醛缩合而得〕。通过ＩＲ、元素分析、电导测定和ＵＶ的表征，可知这两个配合物具有一个内源桥和一个外源桥。测定了这两个配合物的变温磁化率（４Ｋ—３００Ｋ）并将实测值与Ｈｅｉｓｅｎｂｅｒｇ模型导出的磁化率方程拟合，得到两个配合物的磁参数，表明这两个双核Ｃｏ（Ⅱ）配合物具有较弱的反铁磁交换作用。

| Abstract: | Two binuclear Co(Ⅱ)complexes were synthesized, namely Co2LBr3CH3CH3OH(1)and Co2L(SCN)3CH3CH2OH(2).(where HL was 1 :2 Schiff base derived from 1,3-diaminopropan-2-ol and picolinadehyde N-oxide).Based on IR,elemental analysis,conductivity measurement,these complexes were proposed to have an endogenous bridge and an exogenous bridge. The complexeswere characterized by variable temperature magnetoc susceptibility (4K～300) and the data werefitted by the least squares to a susceptibility equation derived from Heisenberg model.The result indi-cated that a weak antiferromagnetic exchange was present in the binuclear Co(Ⅱ)complexes. |
