利用水热法,通过Cu(Ⅱ)与2,2′-联咪唑(H2biim)的协同作用,合成了一个新的超分子配合物。通过元素分析,红外光谱和X射线单晶衍射对其组成、结构进行了研究。H2biim配体采用了双齿螯合方式与金属铜离子配位。多种氢键和H2biim配体之间的π-π堆积作用共同构筑得到了配合物的超分子网络结构。热重分析表明,联咪唑铜配合物具有良好的热稳定性。并对合成条件进行了探讨。
A new supramolecular complex was synthesized by the synergism of Cu (Ⅱ) with 2,2’-biimidazole (H2biim) by hydrothermal method. Its composition and structure were studied by elemental analysis, IR and single crystal X-ray diffraction. H2biim ligands adopt a double-chelate chelation method to coordinate with metal copper ions. Π-π stacking between a variety of hydrogen bonds and H2biim ligands to construct the supramolecular network structure of the complex. Thermogravimetric analysis shows that the biimidazole copper complex has good thermal stability. The synthesis conditions were also discussed.
