摘要:
以N,N'-双(3-氨基-2,2-二甲基丙基)草酰胺根阴离子(Me2oxpn)为桥联配体,分别端接N,N,N',N'-四甲基乙二胺(tmen)和2,9-二甲基-1,10-邻菲罗啉(Me2-phen);合成和表征了3种新的异双核配合物[Cu(Me2oxpn)Fe(tmen)2]SO4(a),[Cu(Me2oxpn)Zn(tmen)2]SO4(b)和[Cu(Me2oxpn)Zn(Me2-phen)2]SO4(c).经元素分析、红外光谱、电子光谱、电导及磁性测量等方法推定了这些配合物的结构.测定并研究了(a)的变温磁化率(4~300K),求得交换参数J=-12.96cm-1,表明双核配合物中Cu(Ⅱ)-Fe(Ⅱ)离子间存在反铁磁超交换作用.测试了3个双核配合物的杀菌作用.

Synthesis,Magnetism and Antibacterial Activity of μ-Oxamido Hetero-binuclear Copper(Ⅱ)-Iron(Ⅱ) and Copper(Ⅱ)-Zinc(Ⅱ) Complexes
Abstract:
Three new _-oxamido heterobinuclear complexes bridged by N,N'-bis(3-amino-2,2-dimethylpropyl)oxamido dianion (Me2oxpn) and end capped with N,N,N',N' tetramethylethylene diamine (tmen) and 2,9-dimethyl-1,10-phenanthroline (Me2-phen), respectively; namely,[Cu-(Me2oxpn)Fe(tmen)2]SO 4(a),[Cu(Me2oxpn)Zn(tmen)2]SO4(b) and[Cu(Me2oxpn)Zn(Me2-phen)2]SO4(c), have been synthesized and characterized by elemental analyses, magnetic moment and molar conductivity measurements, and spectrometry. These complexes appeared to have oxamido bridged structures consisting of planar copper(Ⅱ) and octahedral iron(Ⅱ) ions. The temperature dependence of magnetic susceptibilities of the complex (a) has been measured at 4~300 K, giving the exchange integral J=-12.96 cm-1. The results indicated the existence of antiferromagnetic superexchange interactions between the metal ions. The antibacterial activity of the complexes was also examined.
