摘　　要：采用水热法合成得到了单核锌配合物[Zn(H2L)(phen)2(H2O)]·4H2O(1)(H2L2-=4,5-二羟基苯-1,3-二磺酸根离子,phen=1,10-邻菲罗啉)。采用X射线单晶衍射、元素分析、红外光谱、热重分析等对配合物进行了结构和组成表征。单晶衍射研究表明,化合物1中Zn2+是6配位的,与2个phen配体的4个氮原子以及水分子和磺酸基氧原子配位,形成扭曲的八面体配位构型。配合物的荧光发射峰与配体相比发生了红移,最大发射峰在523nm。The mononuclear zinc complex[Zn(H2L)(phen)2(H2O)] 4H2O(1)(H2L2-=4,5-dihydroxy-1,3-benzenedisulfonate,phen=1,10-phenanthroline)is synthesized by hydrothermal method.The composition and structure of the complex are characterized by X ray single crystal diffraction,elemental analysis,infrared spectroscopy and thermogravimetric analysis.The single crystal diffraction study show that the Zn 2+is six-coordinated,which coordinates with the four nitrogen atoms of two phen ligands and the oxygen atoms of water molecule and sulfonate group,and forms the twisted octahedral configuration in the compound 1.Compared with the ligand,the fluorescence emission peak of the complex has a red shift,and the fluorescence emission has a red shift compared to the ligand,its maximum peak is at 523nm.
