摘　　要：通过pH调控的水热法合成了2种配合物[Ag(H2btc)(bpy)](1)和[Cd(Hbtc)(bpy)(H2O)2]n (2)(H3btc=1,2,4-苯三甲酸,bpy=2,2′-联吡啶),并通过X射线单晶衍射、红外光谱、热重分析、荧光光谱进行了表征与性质研究。结果表明,配合物1为零维的单核小分子结构,配合物2为一维的链状结构。荧光研究表明,这2种配合物均具有荧光性质。Two complexes,[Ag(H2btc)(bpy)](1) and [Cd(Hbtc)(bpy)(H2O)2]n (2)(H3btc=1,2,4-benzenetricarboxylic acid, bpy=2,2′-bipyridine), were synthesized under pH-controlled hydrothermal conditions and characterized by X-ray single crystal diffraction, IR spectra, thermal gravimetric analysis (TGA) and fluorescence spectroscopy. The results show that complex 1 is a zero-dimensional mononuclear small molecule structure, and 2 is a one-dimensional chain structure. Fluorescence studies showed that both complexes have fluorescent properties. CCDC: 1872165, 1;1872166, 2.
