摘要: 合成了以双吡唑桥联的双核铜配合物的3个同系物。利用吡唑-3,5-二(N-甲基甲酰胺)合硝酸铜双聚物的粉末ESR谱计算了g和g。变温磁化率的实验数据拟合表明了它们均为有较强反铁磁性的化合物,用半经验分子轨道方法分析了它们的磁交换途径。

Abstract: Three analogous compounds of dinuclear copper complexes with bridged pyrazole molecules were synthesizedThe ESRspectrum of [((Pz)-3, 5-(CONMe)2Cu)2(H2O)(NO3)](NO3) powder was used to estimate the values of g and gThen the experimental data of variable temperature susceptibility were fitted to the Bleaney-Bowers equation and the results show that the magnetic properties of the three compounds are all strongly antiferromagneticSemiempirical MOmethod was used to analyze their magnetic exchange paths.

Key words: Pyrazole, Dinuclear copper complex, Antiferromagnetism
