A series of lanthanide coordination polymers constructed from 4-pyridin-4-ylbenzoate

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,...
