摘要
Four lanthanide coordination polymers, LaLa（HzO）2（1）, LnL2（μ3-OH）（H2O）[Ln=Eu（2）,Tb（3）] and ErL32H2O（4） were synthesized via hydrothermal reactions of lanthanide oxide with 4-pyridin-4-ylbenzonic acid（HL）, and characterized by means of elemental analyses, infrared（IR） spectrometer, powder X-ray diffraction（PXRD）, thermogravimetric analyses（TGA） and single-crystal XRD. The results reveal that complex 1 possesses a linear chain structure, complexes 2 and 3 possess isostructural ladder-like chains, while complex 4 possesses a 2D layer with 4-connected sql topology. Furthermore, the luminescence properties and UV-Vis spectra of complexes 2 and 3 were investigated.
