摘　　要：利用芳香柔性多元酸N,N,N’,N’-对苯二甲基二胺四乙酸(H4L)与Cu(NO3)2反应构筑了一种多核铜配合物.对该配合物的单晶进行了X-射线晶体结构分析,表明该配合物属于正交晶系,空间群为Pmn21.该配合物呈现出了空间三维框架结构,其中长方形孔道大小为1.105 6 nm×0.696 4 nm.电喷雾质谱(electro spray ionization-mass spectrometry,ESI-MS)及电位滴定结果显示,该多核铜配合物在溶液中可以双核铜单体配离子的形式存在.对该多核铜配合物的固体及溶液配位行为的研究可为该类物质在磁性材料、催化及金属酶的结构及功能模拟方面提供理论依据.Reaction of the N,N,N＇,N＇-p-xylylenediamine tetracetic acid（H4L） with Cu（NO3）2 leads to the formation of a new polynuclear copper complex. Crystal structure of the polynuclear copper complex has been determined. This polynuclear copper complex belongs to the orthorhombic space group Pmn21, and exhibits a novel 3 D structure. Rectangular channels with a dimension of 1.105 6 nm×0.696 4 nm, based on the distances of Cu ions, are found in this structure. Additionally, the results of electro spray ionization-mass spectrometry（ESI-MS） spectra and potentiometric measurements show that the polynuclear copper complex exists as a dinuclear species in the solution. The results may provide theoretical basis to potential applications of the polynuclear copper complex in magnetism, catalysis and structural and functional models of metalloenzymes.
