| 摘要: 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=1.113 992(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。 |

| Abstract: (-)-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, b=1.804 972(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. |
