Abstract Four novel lanthanide(III) coordination polymers [Ln(L)1.5(H2O)2]·5H2O [Ln = Sm (1), Eu (2), Tb (3), Dy (4)] have been hydrothermally synthesized by the reaction of 1,2-bis[4-amino-5-carboxylmethylthio-(1,2,4-triazol-3-yl)]ethane (H2L) with lanthanide(III) salts, and structurally characterized by single crystal X-ray diffraction. Polymers 1–4 are isostructural, in which all the LnIII atoms
摘要 四种新型镧系元素(III)配位聚合物 [Ln(L)1.5(H2O)2]·5H2O [Ln = Sm (1), Eu (2), Tb (3), Dy (4)] 1,2-双[4-氨基-5-羧基甲硫基-(1,2,4-三唑-3-基)]乙烷(H2L)与镧系元素(III)盐的反应,结构特征为单晶X-射线衍射。聚合物 1-4 是同构的,其中所有的 LnIII 原子都是九配位的,羧酸根采用三种不同的配位模式(双齿螯合、双齿桥连、双齿螯合桥连)来连接 LnIII 原子。这些聚合物表现出具有 2 倍互穿的 3D 网络结构,其中观察到有趣的 1D 通道。此外,研究了标题聚合物的光谱性质,发现了2-3的强发光特性。
