Abstract
Two new coordination polymers [Dy3(PDA)4(HO)(H2O)2]·6H2O (1) H2[(H3O)Sm3(PDA)6]·14H2O (2) (H2PDA = 2,4-pyridinedicarboxylic acid), have been hydrothermally synthesized and characterized by elemental analysis, IR, TG, XRD as well as single-crystal X-ray diffraction. They display different three-dimensional coordination frameworks, in which 2,4-PDA exhibits μ4-(κ5N,O2:O2′:O4:O4′), μ4-(κ5N,O2:O2,O2′:O4:O4′) and μ1-(κ5N,O2) coordination modes. Their topological structures have been analyzed. It is interesting that they have the same topological structure. The luminescence properties of 1 and 2 were determined with solid samples. They show the exclusive luminescence emission of Dy(III) or Sm(III) ions, respectively. The magnetic properties of 1 were also studied. It displays antiferromagnetic Dy(III)···Dy(III) interactions. CCDC 1945187 and 1945188 for complexes 1 and 2, respectively.
