摘　　要：以均苯三甲酸、邻菲罗啉为配体,以六水合硝酸钴为金属离子源,六水合硝酸铈作为催化剂,采用水热法合成了一种新颖结构的钴基配合物。通过X射线单晶衍射仪确定了其结构,采用红外光谱仪、紫外光谱仪及热重分析等手段对其进行了表征。结果表明:所合成的晶体属于单斜晶系,空间群为C2/c,钴离子与邻菲罗啉配位,晶格中存在均苯三甲酸分子。配合物的分子式为C81H52CoN7O34,且在240℃之前可以稳定存在,说明了配合物具有较好的稳定性。A novel Co-based complex was prepared by hydrothermal method with trimesic acid and o-phenanthroline as the ligands, cobalt nitrate hexahydrate as the metal ion source and cerium nitrate hexahydrate as the catalyst. Its structure was determined by X-ray single crystal diffractometer, and it was characterized by infrared spectrometer, ultraviolet spectrometer and thermogravimetric analysis. The results show that the synthesized crystals belong to the monoclinic system and the space group is C2/c. The cobalt ion is coordinated with o-phenanthroline molecule, and the trimellitic acid molecules exist in the crystal lattice. The molecular formula is expressed by C81H52CoN7O34. The complex can exist stably below 240 ℃, indicating its better stability.
