|
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-chlorophenoxyacetylhydrazone was obtained through the theory of molecular modification by the 4-chlorophenoxyacetic acid.The few novel five-coordinate copper hydrazone complex of Cu[C11H13ClN2O2]2O 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/c.The copper(Ⅱ) is coordinated with nitrogen atom and oxygen atom of hydrazone ligands,forming two stable five-member rings structure,and showing a cone of copper ions to the top of the pyramid structure.Oxygen(3) atom of μ-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.
