摘　　要：以合成具有优良性能的3D框架配合物为目的,选用四羧酸类6-硝基-[1,1′-联苯]-2,2′,4,4′-四羧酸(H4L)和1,2-双(4-吡啶基)(bpa)乙烷作为配体,与过渡金属Co在水热条件下合成一例具有新颖结构的配位聚合物.通过SXRD、TGA、FTIR、PXRD对其结构和性能进行了表征.分析表明配合物具有一维链结构,通过6-硝基-[1,1′-联苯]-2,2′,4,4′-四羧酸配体连接形成3D框架.配合物表现出良好的热稳定性和反铁磁性.In order to synthesize complex with 3D frameworks,tetrakisocarboxylic acid 6 ni tro [1,11 biphenyl] 2,21, 4,41 tetracarboxylic acid（H4L） and 1,2 his （4 pyridyl） ethane （bpa） as ligand,and transition metal Co under hydrothermal conditions to synthesize a novel and unique structure. The structure and properties of the complex was characterized by SXRD, TGA, FTIR and PXRD. The analysis shows that the complexes have a one dimension al chain structure and the 3D framework is formed through the linkage of 6 nitro [1,11 bi phenyl] 2,21, 4,41 tetracarboxylic acid ligands. The complexes show good thermal stability and antiferromagnetic properties.
