【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.更多还原
