Abstract:

Four lanthanide coordination polymers, LaL3(H2O)2(1), LnL2(μ3-OH)(H2O)[Ln=Eu(2),Tb(3)] and ErL3·2H2O(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.
