本文报道了六个镉（II）与咪唑-4，5-二甲酸丙酯（H3 PIDC）的配合物，包括两个单核配合物[Cd（H2 PIDC）2（H2O）2]·4 H2O（1）和[Cd 2（H2 PIDC）4（H2O）4]·7 H2O（2），两个四方四核配合物[Cd 4（HPIDC）4（H2O）8]·2 H2O（3）和[Cd 4（HPIDC）4（py）8]·10 H2O采用溶剂蒸发法和水热法合成了一维链状聚合物[Cd（H2 PIDC）2]n·2nH 2 O（5）和二维层状聚合物[Cd（H2 PIDC）2]n（6）。单晶X射线衍射分析结果表明，除了氢键和π···π堆积等常见的超分子相互作用外，H3 PIDC配体中丙基之间的疏水相互作用也对1-6的稳定性有贡献. 3的物质转化研究表明，吡啶分子可以很好地取代3中的配位H2O分子，间接导致4的形成。光致发光测量的结果IL…
Six cadmium(II) coordination compounds with 2-propyl-imidazole-4,5-dicarboxylate (H3PIDC), including two mononuclear complexes, [Cd(H2PIDC)2(H2O)2]·4H2O (1) and [Cd2(H2PIDC)4(H2O)4]·7H2O (2), two square tetranuclear complexes, [Cd4(HPIDC)4(H2O)8]·2H2O (3) and [Cd4(HPIDC)4(py)8]·10H2O (py = pyridine, 4), one one-dimensional chain polymer, [Cd2(H2PIDC)4(H2O)2]n·2nH2O (5), as well as one two-dimensional layer polymer, [Cd(H2PIDC)2]n (6), have been prepared using solvent evaporation method and hydrothermal method. The results of single-crystal X-ray diffraction analyses indicate that, besides the common supramolecular interactions such as hydrogen bond and π···π stacking, the hydrophobic interaction among the propyl groups in the H3PIDC ligands also contributes to the stabilities of 1–6. The study of substance transformation for 3 reveals that the coordinated H2O molecules in 3 can be well replaced by pyridine molecules, indirectly leading to the formation of 4. The results of photoluminescent measurements il...
