| Abstract: Hydrothermal assembly reactions of Zn(NO3)2·6H2O, 1,5-bis-(2-methyl-imidazol)pentane (BMIP) and 5-hydroxyisophthalic acid (5-OHH2IP) or 5-bromoisophthalic acid (5-BrH2IP) ligands resulted in the formation of complexes[Zn(5-OHIP)(BMIP)]n (1) and[Zn(5-BrIP)(BMIP)]n (2), respectively. The resulting complexes were characterized by IR spectrum, elemental analysis and single-crystal X-ray diffraction. Crystal structure analysis shows that complex 1 crystallizes in the monoclinic system, space group P21/n with β=101.363(10)°. Complex 1 displays a two-dimensional layer net constructed by 5-hydroxyisophthalic acid and 1,5-bis-(2-methyl-imidazol)pentane. For 2, 5-bromoisophthalic acid and 1,5-bis-(2-methyl-imidazol)pentane link Zinc ion into a two-dimensional layers, which are pillared by the other BMIP ligands to result in the three-dimensional framework from another direction. Finally, it exhibits a fascinating three-fold interpenetrating net with dmp topology. Both complexes exhibit a strong photolu-minescence in the solid state at room temperature. Moreover, two complexes present good photocatalytic activities in methylene blue (MB) degradation reactions. |
