摘要 水热条件下合成新的超分子配合物——5-硝基水杨醛缩乙二胺双希夫碱铜(II)配合物.通过元素分析、红外光谱和X射线单晶衍射等手段对其组成、结构进行了表征.结果表明,配体采用四齿螯合的方式与金属铜离子配位,所得到配合物结构单元之间通过π-π堆积作用形成了超分子网络结构.配合物具有良好的热稳定性. A new supramolecular copper(Ⅱ)complex with bis-schiff base derived from 5-nitro salicylic aldehyde and ethylenediamine is synthesized under hydrothermal condition.Its composition and structure is characterized by means of elemental analysis,infrared spectroscopy,and x-ray crystal diffraction.The structure shows that the ligand is coordinated with metal copper ion in a way of four-teeth-chelating,and the coordination compound construction unit obtained forms supramolecular network of ligand throughπ-πstacking.The synthesized compound has good thermostability.
