摘要: 利用混合配体(H2tda=亚硫基二乙酸, H2ox=乙二酸, phen=1,10-菲咯啉)与CeCl3·5H2O反应,合成了新型稀土配合物[Ce(tda)(ox)0.5(phen)]n,单晶结构分析表明:配合物以共边的多面体[Ce2O12N4]为基本单元构筑二维结构,并通过π-π堆积作用拓展为三维超分子体系。该二维结构具有(4,5)连接的(46)(44·66)2拓扑结构,在拓扑结构中稀土离子呈现不寻常的5连接点。 |

Abstract: A novel lanthanide coordination polymer with the formulas [Ce(tda)(ox)0.5(phen)]n(H2tda=thiodiglycolic acid, H2ox=oxalic acid, phen=1,10-phenanthroline) have been synthesized and structurally characterized. Single crystal X-ray diffraction studies show that the coordination polymer are a 2D network and exhibit an unprecedented (4,5)-connected (46)(44·66)2 topology, in which the lanthanide ions act as unusual 5-connected nodes, and an edge-sharing dinuclear polyhedral [Ce2O12N4] was found. Furthermore, through strong π-π interactions, the 2D network structure are cross-linked to generate to generate a 3D upramolecular architectures. CCDC: 764100. |
