摘　　要：利用水热法合成了一例新的超分子配合物——5-硝基水杨醛缩乙二胺双希夫碱钴(Ⅲ)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、结构进行了研究,并对合成条件进行了探讨.结果表明,配体采用四齿螯合的方式与金属钴离子配位,配合物结构单元之间通过分子间氢键构筑得到了配合物的超分子网络结构.热重分析表明,配合物具有良好的热稳定性.A new supramolecular Co（Ⅲ）-based complex with N,N＇-bis-5-nitro-salicylidene）-1,2-diaminoethane was synthesized by hydrothermal method.The structure of complex was characterized by elemental analysis,IR and single-crystal X-ray diffraction.X-ray structural analysis showed that the ligand employs chelate mode to link with Co（Ⅲ）ion.The three-dimensional network of complex was formed from hydrogen bonding interaction.The result of thermal analysis demonstrated that the title complex had superior thermo stability.In addition,the synthetic conditions of the complex was discussed.
