A novel 3d–4f heterometallic coordination polymer, namely, {[Sm2(PBDA)2·2H2O][Zn2(PBDA)2(Cl)2]}n (1), (H2PBDA = 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 H2PBDA ligand were also investigated.
