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。
Using the advantages of hydrothermal synthesis of the complex, a 5-aminotetrazole ligand with a specific structure as a ligand and zinc metal ion coordination polymer was constructed. The complex was characterized by IR and X-ray single crystal diffraction Structural characterization and performance studies. Single crystal X-ray diffraction showed that the complex was 2D double-layered structure. Each zinc ion coordinates with the surrounding four 5-aminotetrazole ligands. From the data of bond length and bond angle, we can see that the zinc ion coordination configuration is a distorted tetrahedron. The complex belongs to the orthorhombic, Cmcm space group with a = 1.7973 (4) nm, b = 1.0348 (2) nm, c = 2.0206 (4) nm, Z = 4 and V = 3.7580 = 1.651 (mg / m3), μ = 2.589 (mm-1). The solid-state luminescent properties of the complexes were studied. The results showed that under the excitation of 342nm at room temperature, the compound has the greatest gratitude at 397nm.
