摘　　要：采用水热法成功合成了两个基于2,3,5,6-四氟-二(1,2,4-三氮唑-1-甲基)苯(Fbtx)及1,4-萘二甲酸(H_(2)NDC)混合配体的配位聚合物,分子式分别为{[Co(NDC)(Fbtx)(H_(2)O)_(2)]·0.5H_(2)NDC}_(n)(1,CCDC:1978985)和{[Cu(NDC)(Fbtx)(H_(2)O)]·1.5H_(2)O}_(n)(2,CCDC:1978986),其结构和性能经X-射线单晶衍射、X-射线粉末衍射、红外光谱、热重分析和元素分析等表征。荧光性能测试结果表明:两个配位聚合物均为二维层状结构,结构中氮杂环和芳香羧酸配体均起桥联作用,并与金属中心配位最终形成4^(4)连接sql的拓扑。Two new mixed-ligand coordination polymers based on 2,3,5,6-tetrafluoro-1,4-bis(tridazol-1-ylmethyl)benzene)(Fbtx)and 1,4-naphthalenedicarboxylic acid(H_(2)NDC),namely{[Co(NDC)(Fbtx)(H_(2)O)_(2)]·0.5H_(2)NDC}_(n)(1)and{[Cu(NDC)(Fbtx)(H_(2)O)]·1.5H_(2)O}_(n)(2),were hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction,powder X-ray diffraction,infrared spectroscopy,thermogravimetric analysis and elemental analysis.Single crystal X-ray analysis reveals that both 1 and 2 show two-dimensional(2D)coordination networks and display planar 4^(4)-sql topologies.Moreover,their luminescent properties were also investigated as well.
