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。

关 键 词:钴配合物,N-氧化物,Schiff碱,磁性

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.
Keywords:cobalt complex  N-oxide  Schiff base  magnetism
