摘　　要：对氯苯氧乙酸通过分子修饰得到丙酮缩对氯苯氧乙酰腙,采用水热法合成了新型的五配位丙酮缩对氯苯氧乙酰腙铜配合物,并用IR和X-射线单晶衍射进行了表征.结果表明,配合物属单斜晶系,空间群为C2/c,每个配合物中铜与来自2个酰腙配体的氮原子和氧原子配位,形成了2个稳定的五元环结构,并呈现出以铜离子为顶点的四棱锥构型.配合物中μ—OH提供一个氧O(3)原子与不同配合单元的氮原子和氢原子形成弱的作用力,使得配合物呈现出1D链结构.荧光测试结果表明,标题配合物较配体荧光性增强.Actone 4-cb.lorophenoxyacetylhydrazone was obtained through the theory of molecular modification by the 4-chlorophenoxyacetie acid. The few novel five-coordinate copper hydrazone complex of Cu^C-~I HI~ C1Nz O~ ]zO was synthesized through hydrothermal of new program temperature control method and characterized by IR and single crystal X-ray diffraction. The result of structure analysis indicates that the complex crystallizes in monoclinic with space group C2/e. The copper（Ⅱ） is coordinated with nitrogen atom and oxygen atom of hydrazone ligands,fonning two stable five-member rings structure,and showing a cone of copper ions to the top of the pyramid structure. Oxy- gen（3） atom ofμ-OH are formed weak interaction with nitrogen and hydrogen of the neighbour unit,making the complex showing 2D supramolecular structure. The fluorescence intensity of title complex is more significant than the hydrazone ligand.
