| Abstract: | Two 3-D MOFs, {Co2(oba)2(bmip)]·DMA}n (1) and Cd(1,3-bdc)(bmip)]n (2), where H2oba = 4,4′-oxybis(benzoic acid), 1,3-bdc = isophthalic acid and bmip = 1,3-bis(2-methylimidazolyl)propane, were synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, powder XRD, FT-IR, TGA, and elemental analysis. Complex 1 features a 3-D→3-D twofold interpenetrating framework, and topological analysis shows the framework can be described as a 6-connected uninodal pcu net having the point symbol (412.63). Complex 2 shows a 3-D→3-D threefold interpenetrating network that can be described as a 4-connected uninodal cds net with (65.8) topology. Gas adsorptions of 1 were carried out, and photoluminescent properties of 1 and 2 were also investigated at room temperature. |
