摘要
Hydrothermal reactions of two imidazole derivatives （1,3,5-tib = 1,3,5-tris（1H- imidazol- 1 -yl）benzene, 1,4-bimb = 1,4-bis（1 H-imidazol- 1 -ylmethyl）benzene） and the ZnⅡ cations in the presence of oxalic acid （H2ox） afford two coordination polymers, namely, {[Zn（ox）（1,3,5- tib）]·2（H20）}n （1） and [Znl.5（OX）1.5（1,4-bimb）l.5]n （2）. Their structures have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, and powder X-ray diffraction （PXRD） analyses. Both complexes 1 and 2 are based on the 1D zigzag [Zn（ox）]n chains, and their final structures are controlled by the two different imidazole linkers, which expanded the structure along different directions, finally giving a 3D dia net for 1 and a 2D sql layer for 2. Moreover, the luminescent properties of 1 and 2 have been investigated.
