摘要
通过溶剂热法以Zn(CH_(3)COO)_(2)·2H_(2)O,4′-(2-呋喃基)-3,2′:6′,3″-三联吡啶与对苯二甲酸为原料(物质的量比1∶1∶1),以无水乙醇和H2O为溶剂(体积比1∶1),140℃恒温反应,合成标题配合物[Zn(3263ftpy)2(bdc)]·2(H_(2)O)(3263ftpy=4′-(2-呋喃基)-3,2′:6′,3″-三联吡啶,H_(2)bdc=对苯二甲酸),通过红外光谱、元素分析、粉末单晶衍射、热稳定性分析对其结构进行表征,再通过单晶X-ray衍射对其晶体结构进行了测定。在该配合物中Zn(Ⅱ)分别与2个三联吡啶环上的N原子和另外2个对苯二甲酸上的4个O原子配位,形成六配位八面体结构,通过对苯二甲酸链接形成了Z字形一维链状结构,再通过杂环间的pi-pi相互作用,形成三维网状结构。
The title complex is synthesized with Zn(CH_(3)COO)_(2)·2H_(2)O and 4′-(2-furanyl)-3,2′:6′,3″-terpyridines(3263ftpy)in the presence of terephthalic acid(H_(2)bdc)as raw materials(molar ratio of 1∶1∶1)and anhydrous ethanol and water as solvent(volume ratio of 1∶1)under the solvothermal method at 140℃.The complex is characterized by elemental analysis,IR,PXRD and thermal stability.The crystal structure is determined by single crystal X-ray diffraction.In this complex,the Zinc cation coordinates with two nitrogen atoms from two different tripyridine ligands and four oxygen atoms from two terephthalic carboxylates,forming a Z-shaped one-dimensional(1D)chain.A three-dimensional(3D)network is formed by pi-pi interactionbetween the heterocycles.
