Two 4f-3d heterometallic one-dimensional coordination polymers [ZnEu2(Fur)8·2H2O]n and [ZnTb2(Fur)8·2H2O]n (HFur=α-furancarboxylic acid) with good solubility were synthesized and characterized by infrared spectra, X-ray single crystal and powder diffractions, thermogravimetric and differential thermal analysis, and excitation and emission spectra. The X-ray diffraction analyses revealed that the two complexes are isomorphous. The Zn and Ln atoms are linked into one-dimensional chains by furancarboxylate ligands and the metal atoms are arranged in the ···Zn···Ln···Ln···Zn···Ln···Ln···order. Under the excitation of UV light, these coordination polymers emit intense characteristic luminescence of Eu3+ or Tb3+ ion, respectively. The influence of Zn2+ ion on the luminescence properties was also discussed here.
