The coordination features of an imidazole dicarboxylate ligand, 2-(3-methoxyphenyl)-1H-imidazole-4,5-dicarboxylic acid (m-H(3)MOPhIDC) has been explored. Consequently, seven coordination polymers, namely Sr(m-HMOPhIDC)(H(2)O) (1), Sr(m-H(2)MOPhIDC)(2) (2), Cd(3)(m-H(2)MOPhIDC)(2)(m-HMOPhIDC)(2)(H(2)O)(2) (3), Cu(m-HMOPhIDC)(phen) (phen = 1,10-phenanthroline) (4), Cd(2)(m-HMOPhIDC)(2)(phen)(2) (5) Cd(2)(m-HMOPhIDC)(2)(2,2'-bipy)(2) (2,2'-bipy = 2,2'-bipyridine) (6) and Co(m-HMOPhIDC)(H(2)O)(2) (7) have been hydro(solvo)thermally synthesized by fine control over synthetic conditions, and structurally characterized. X-ray single-crystal analyses reveal that these polymers indicate rich structural chemistry ranging from one-dimensional (4-7), two-dimensional (1 and 3) to three-dimensional (2) structures, and the m-H(3)MOPhIDC ligand in these polymers can be singly deprotonated or doubly deprotonated, and coordinates to metal ions by various modes. The thermal and fluorescence properties of the complexes 1-7 have been determined as well.
探索了一种咪唑二羧酸配体 2-(3-甲氧基苯基)-1H-咪唑-4,5-二羧酸（m-H(3)MOPhIDC）的配位特性。因此，合成了七种配位聚合物，分别为 Sr(m-HMOPhIDC)(H(2)O)（1）、Sr(m-H(2)MOPhIDC)(2)（2）、Cd(3)(m-H(2)MOPhIDC)(2)(m-HMOPhIDC)(2)(H(2)O)(2)（3）、Cu(m-HMOPhIDC)(phen)（phen = 1,10-菲啰啉）（4）、Cd(2)(m-HMOPhIDC)(2)(phen)(2)（5）、Cd(2)(m-HMOPhIDC)(2)(2,2'-bipy)(2)（2,2'-bipy = 2,2'-联吡啶）（6）和 Co(m-HMOPhIDC)(H(2)O)(2)（7）。通过精细控制合成条件，采用水（溶剂）热合成法合成了这些聚合物，并对其结构进行了表征。X 射线单晶分析表明，这些聚合物具有丰富的结构化学，包括一维（4-7）、二维（1 和 3）到三维（2）结构，并且这些聚合物中的 m-H(3)MOPhIDC 配体可以单质子化或双质子化，并通过各种模式与金属离子配位。还测定了配合物 1-7 的热和荧光性质。
