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。
In this paper, two dinuclear cobalt (Ⅱ) complexes, Co2LBr3 · CH3CH2OH (1) and Co2L (SCN) 3 · CH3CH2OH (2) Pyridine-2-carboxaldehyde condensation]. By IR, elemental analysis, conductivity measurement and UV characterization, we know that these two complexes have one endogenous bridge and one exogenous bridge. The temperature-dependent magnetic susceptibility (4K-300K) of the two complexes was determined and the measured values were fitted to the susceptibility equations derived from the Heisenberg model to obtain the magnetic parameters of the two complexes, indicating that the two binuclear Co (II) complexes The material has a weaker antiferromagnetic exchange effect.
