| Abstract: | Two new metal-organic frameworks, Zn2(FA)2(bix)2]n · 3nH2O (1) and Zn(FA)(bib)]n (2), (H2FA = fumaric acid, bix = 4,4′-bis(imidazol-1-ylmethyl)benzene, bib = 1,4-bis(imidazolyl)butane), have been synthesized by combining the fumaric acid and flexible imidazole-based ligands with Zn(II) salts under hydrothermal conditions. Single-crystal X-ray diffraction analysis reveals that 1 is a 4-fold interpenetrated unc topological net, and 2 is a 5-fold interpenetrated dia topological net. Moreover, the luminescent properties of the two compounds were also investigated in the solid state at room temperature. |
