(-)-2,2'-[thiophene-2,5-diylbis(carbonylimino)]dipropanoic acid (C12H14N2O6S) and 4,4'-dipyridine (4,4'-bipy) were used as ligands to react with Eu3+ ion to obtain a complex {[Eu2(C12H12N2O6S)3(4,4'-bipy)(H2O)2]·(H2O)6}n. The coordination polymer has been hydrothermally synthesized and characterized by X-ray single crystal diffraction. The complex crystallizes in orthorhombic system, lattice parameters a=1.113 992(18) nm, 6 = 1.804972(19) nm, c= 2.933 80(3) nm, Z=4. The coordination number of Eu3+ ion is eight and nine. The emission spectrum of the solid-state complex was determined, which show the typical photo-induced luminescence of Eu3+. The ligand in the complex can enhance the luminescence of rare earth. The complex was studied by TG-DTA analysis. CCDC: 824360.%以(—)-2,2'-(2,5-噻吩二甲酰氨基)二丙氨酸(C12H14N2O6S)及4,4'-联吡啶(4,4'-bipy)为配体,在水热条件下合成了铕配位聚合物{[Eu2(C12H12N2O6S)3(4,4'-bipy)(H2O)2]· (H2O)6}n.通过X-射线单晶衍射仪测定其结构,结果表明:晶体为正交晶系,晶胞参数a=1.113992(18) nm,b=1.804 972(19) nm,c=2.933 80(3) nm,Z=4;2个Eu原子分别为九和八配位.测定发现配合物固体具有Eu3+的典型光致发光光谱,配合物中配体能有效提高稀土离子的发光效果.并通过热重分析对配合物进行了热稳定性研究.
