摘　　要：基于4-氯-6-[2-(吡嗪-2-亚甲基)-肼基]嘧啶配体,合成了一种含氮杂环Schiff碱锌配合物,并采用X-射线单晶衍射(XRD)、核磁氢谱(^(1)H NMR)、元素分析、X射线粉末衍射(XRD)及热重等测试手段进行了结构表征。采用荧光光谱法研究了含氮杂环Schiff碱锌配合物对不同金属离子的识别性能,结果表明配合物能很好地对Cu^(2+)进行选择性识别。Zn(Ⅱ)Schiff base complex containing nitrogen heterocyclic based on ligand of 4-chloro-6-[2-(pyrazin-2-ylmethylene)hydrazinyl]pyrimidine(HL)has been successfully synthesized and characterized by X-ray single crystal diffraction,^(1)H NMR,elemental analysis,powder X-ray diffraction(PXRD)analyses and thermo gravimetric studies.The recognition performance of the nitrogenous heterocyclic Zn(Ⅱ)Schiff base complex for different metal ions was studied by fluorescence spectroscopy.The results show that the complex can selectively recognize of Cu^(2+).
