| Abstract: | Two new metal-organic frameworks (MOFs),[Cu2(H2O)2(BCPIA)] (BUT-20) and (Me2NH2)[In(BCPIA)] (BUT-21) were designed and synthesized through the solvothermal reaction between a newly created desymmetric 4-connected ligand, 5-(2, 6-bis(4-carboxyphenyl)pyridin-4-yl)isophthalic acid (H4BCPIA) and Cu(NO3)2·2.5H2O or In(NO3)3·5H2O, respectively, and characterized by single-crystal and powder Xray diffraction, thermogravimetric analysis, infrared spectroscopy, and elemental analysis. The two MOFs have three-dimensional structures, in which both the BCPIA4-ligand and metal-containing entities, Cu2(COO)4(H2O)2 and In(COO)4 act as 4-connected nodes. However, different linkage configurations of the two metal-containing nodes, quadrilateral Cu2(COO)4(H2O)2 and tetrahedral In(COO)4, lead to distinct structural networks of BUT-20 and -21, with Nbo and Unc topologies, respectively. |
