摘要
2-(对氟)苯基-4,5-咪唑二羧酸(p-FPhH3IDC)与2,2'-联吡啶(2,2'-bipy)在溶剂热条件下与Cd(Ⅱ)反应,合成了一个三维超分子[Cd(p-FPh H_2IDC)_2(2,2'-bipy)](配合物1).通过元素分析、红外光谱以及单晶衍射技术对配合物1进行了表征,结果表明,配合物1构筑块在分子间氢键的作用下形成无限长链,随后在π-π堆积作用下形成二维层,进而通过范德华作用力连接成三维的固态堆积结构.配合物1热稳定性良好,在345.5℃前不分解.
By employing 2-（ p-fluorophenyl）-1H-imidazole-4,5-dicarboxylic acid （ p-FPhH3IDC） and 2,2′-bipy,to react with cadmium（Ⅱ） ion, a new supramolecule [Cd（p-FPhH2IDC）2 （2,2′-bipy）] （ complex 1） was successfully synthesized. Complex 1 was characterized by elemental analysis, IR spec-troscopy and single crystal X-ray diffraction. In complex 1, the [Cd（p-FPhH2IDC）2（2,2′-bipy）] units were joined through intermolecular hydrogen bonds to form a 1D chain. Then the 2D sheets were formed by π-πinteractions between the chains. Finally, these sheets were piled up into a 3D solid-state structure by the strong intermolecular interactions. Complex 1 indicated good thermal stability below 345. 5 ℃.
