Lanthanide(III) Coordination Polymers with Longer-Spanning Flexible Ligand: Synthesis, Crystal Structure and Luminescence Property

Two new two-dimensional (2D) lanthanide-organic frameworks [Ln (C10H16O4)1.5(H2O)2][Ln = Tb(1), Eu(2)] have been synthesized and characterized by elemental analyses, IR, XRD, and the X-ray diffraction. And the X-ray diffraction result shows that complex 1 is nine-coordinate and connected through the carboxylate groups of sebacate ligands to generate an extended 2D layer structure. Furthermore, the thermogravimetric analyses of complex 1 and the luminescent properties of all the complexes were carried out.
