Then the hydrolysis product(1-[bis(4-carboxylphenyl)methyl]-1,2,4-triazole, H2ltzda) reacted with Co(NO3)2·6H2O in the presence of different bipyridl-typed ligands under hydrothermal conditions. As a result, two new Co(Ⅱ) MOFs were obtained, formulated as [Co2(ltzda)2(bpp)2]n(1) and {[Co2(ltzda)2(bpy)]·4H2O}n(2)(bpp = 1,3-di(4-pyridyl)propane, bpy = 4,4’-bipyridine). Two MOFs have been characterized by single-crystal X-ray diffraction, thermogravimetric analysis and magnetic measure. 1 displays a 2D metal-organic framework containing wave layers and 2 shows a pillared-layer structure existing in a 2-fold interpenetrated mode.展开更多
