| 摘要: 合成了两种新的双核配合物[Cu2(IPHTA)(Me2bpy)2](ClO4)2(a)和[Cu2(IPHTA)(NO2-phen)2](ClO4)2(b),IPHTA代表间苯二甲酸根二价阴离子;Me2bpy和NO2-phen分别表示4,4′-二甲基-2,2′-联吡啶和5-硝基-1,10-邻菲罗啉。并通过元素分析、红外光谱、可见-紫外光谱、ESR谱及电导等对配合物进行了表征;基于变温磁化率测量和自旋哈密顿算符(H=-2JS1·S2)已推出交换积分J=2.36cm-1(NO2-phen)和J=16.2cm-1(Me2bpy),表明两个双核配合物中Cu(Ⅱ)和Cu(Ⅱ)离子间为铁磁偶合。 |

| Abstract: Two novel copper (Ⅱ) binuclear complexes have been synthesized,namely [Cu2(IPHTA)(L)2](ClO4)2,[L denotes 4,4′-dimethyl-2,2′-bipyridine (Me2 bpy) and 5-nitro-1,10-phenanthroline (NO2 phen),respectively],where IPHTA is the isophthalato dianion. They are characterized by elemental analyses,IR spectra,electronic spectra,ESR and conductivity measurements. The temperature dependence of magnetic susceptibilities of complexes has been studied,and the exchange integral JCu-Cu is found to be 2.36 cm-1 for [Cu2(IPHTA)(NO2phen)2](ClO4)2 and 16.2 cm-1 for [Cu2(IPHTA)(Me2 bpy)2](Cl O4)2,on the base of spin Hamiltonian H=2JS1·S2. The resultsare commensurate with ferromagnetic interactions between Cu(Ⅱ) ions. |
