摘　　要：以4′-二茂铁基-3,2′:6′,3″-三联吡啶为配体,和AgPF_(6)合成了一种新型银配合物Ag_(2)L_(2)(PF_(6))_(2),配合物经红外光谱、元素分析和单晶X射线衍射进行表征。晶体结构分析表明,配合物为三斜晶系,Pī空间群,配体采用顺式-顺式结合形式配位,Ag^(+)配位数为2,配合物为[2+2]金属环状。通过对配合物的紫外可见光谱进行Kubelka-Munk函数计算,配合物带隙为1.90 eV,具有半导体性质。A novel Ag-based coordination compound,Ag2L2(PF6)2,has been synthesized based on 4′-ferrocenyl-3,2′:6′,3″-terpyridine with Ag PF6,and characterized by means of FT-IR,elemental analysis,and the single-crystal X-ray diffraction analysis.The results of the crystal structure analysis show that the coordination compound is a[2+2]metallocycle,in which the ligands adopt the cis-cis binding modes and the Ag+is two-coordinated,and crystalizes in the triclinic crystal system with Pispace group.Furthermore,the optical band gap(1.90 e V),measured by the UV-Vis diffuse reflectance spectroscopy with Kubelka-Munk function,reveals that the complex is expected to have semiconductor property.
