摘要

A novel supramolecular complex [Cd（phen）3]（H2abtc）·0.5（H4abtc）·CH3OH（1）（phen=1,10-phenanthroline hydrate,H4abtc=3,3′,4,4′-azobenzenetetracarboxylic acid） has been synthesized in situ reaction of 3,3′,4,4′-azobenzenetetracarboxylic acid and 1,10-phenanthroline hydrate with a Cd（II） salt and structurally characterized by single crystal X-ray diffraction and fluorescence spectrum.In the complex,the Cd atoms take six-coordinated with six N atoms from three phen forming distorted octahedral geometry.Interestingly,the structure of the complex 1 exhibits interesting one-dimensional Z chain networks and two-dimensional networks were formed by hydrogen bonds（O-H…O and C-H…O）.%利用3,3＇,4,4＇-偶氮苯四甲酸、邻菲啰啉与醋酸镉反应得到了一种新型超分子配合物[Cd（phen）3（]H2abtc）.0.5（H4abtc）.CH3OH（1）（phen=邻菲啰啉,H4abtc=3,3＇,4,4＇-偶氮苯四甲酸）,并通过X-射线单晶衍射分析、元素分析和荧光光谱对它进行了表征。结果表明,配合物1的镉原子与三个邻菲啰啉的六个N配位构成一个扭曲的八面体结构,配体3,3＇,4,4＇-偶氮苯四甲酸未参与配位。分子间通过氢键构成了1D的Z字链结构,而1D链之间通过O-H…O和C-H…O形成2D的网络结构。
