| 摘要: 由水热法合成了2个微孔镧系超分子配合物[Ln(CCA)(OH)(phen)(H2O)]n·n(phen)·nH2O(Ln=Yb,1;Er,2;H2CCA=2-羧基肉桂酸;phen=1,10-菲啰啉),并用元素分析、IR及X-射线单晶衍射对其进行了表征。晶体结构研究表明,2个配合物都是由配体2-羧基肉桂酸连接而形成的一维双链结构,该链状结构通过氢键和π-π堆积作用扩展为具有微孔结构的超分子。1,10-菲啰啉在微孔结构的形成过程中起到了模板剂的作用。 |

| Abstract: Two microporous lanthanide supramolecular complexes [Ln(CCA)(OH)(phen)(H2O)]n·n(phen)·nH2O(Ln=Yb, 1; Er, 2; H2CCA=2-carboxycinnamic acid; phen=1,10-phenanthraline) were obtained through hydrothermal reaction and characterized by elemental analysis, IRand single-crystal X-ray diffraction. The results show that the two complexes are isostructural and in the two complexes, dinuclear Ln2(OH)2 units are linked by CCA2-ligands to form 1Dinfinite double-stranded chains. There are two kinds of phen ligands. One adopts a chelating-bidentate coordination mode, the other is not involved in the coordination and acts as templating ligands, which leads to the formation of supramolecular networks with microporous structures.
