摘要：

A novel 3d-4f heterometallic coordination polymer, namely, {[Sm-2(PBDA)(2)center dot 2H(2)O][Zn-2(PBDA)(2)(Cl)(2)]}(n) (1), (H(2)PBDA = 3 -(pyridin-3-yl-oxy) benzene -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 H(2)PBDA ligand were also investigated.
