【摘要】 利用水热法合成配合物的优点,构筑了一个具有特定结构的5-氨基四唑为配体与锌金属离子配位聚合物,用红外光谱、X-射线单晶衍射等技术对配合物进行了结构表征和性能研究。单晶X-射线衍射显示配合物为2D双层结构。每一个锌离子与周围的四个5-氨基四唑配体进行配位,由键长和键角的数据可以看出锌离子的配位构型是有些扭曲的四面体构型。该配合物属于正交晶系,Cmcm空间群,a=1.7973(4)nm,b=1.0348(2)nm,c=2.0206(4)nm,Z=4,V=3.7580(13)nm3,D=1.651(mg/m3),μ=2.589(mm-1)。对配合物的固态的发光性质进行了研究。结果表明,在室温342nm激发下,配合物在397nm处有最大发谢。更多还原

【Abstract】 The hydrothermal method was used to synthesize a special coordination compound of zinc ion linked by 5-aminotetrazole ligands with an unique structure.The complex was characterized by FT IR spectroscopy and single crystal X-ray diffraction.The crystal structure of the complex determined by X-ray diffraction is a 2D double-layer structure,belonging to orthorhombic crystal system with space group Cmcm,a=1.7973(4)nm,b=1.0348(2)nm,c=2.0206(4)nm,Z=4,V=3.7580(13)nm3,D=1.651mg/m3,μ=2.589mm-1.The central zinc(Ⅱ)cation is coordinated with four 5-aminotetrazole ligands in a distorted tetrahedral configuration.The luminescent properties of the solid complex were studied,which showed that when excited under room temperature at 342nm the emission maximum appeared at 397nm.更多还原
