摘要

A novel 3d-4f heterometallic coordination polymer, namely, {[Sm₂(PBDA)₂路2H₂O][Zn₂(PBDA)₂(Cl)₂]}_n (1), (H₂PBDA = 3 -(pyridin-3-yl-oxy) benzene 鈭?#xA0;1,2-dicarboxylic acid) has been hydrothermally synthesized by using samarium(III) nitrate, H₂PBDA acid and zinc chloride as raw materials, and characterized by elemental analysis, FT-IR, TG analysis and single crystal X-ray diffraction. Polymer 1 possesses two-dimensional (2D) network containing the original 1D heterometallic chain composed of [Sm₂Zn₂(PBDA)₂] moieties. Variable temperature magnetic susceptibility studies reveal that 1 displays possible weak antiferromagnetic coupling between the neighboring Sm(III) ions, and the photoluminescent properties of polymer 1 as well as free H₂PBDA ligand were also investigated.
