Abstract


Three coordination polymers, [Cd(L)2(H2O)2]n (1), [Zn(L)2(H2O)2]n (2) and  [Mn(L)2]n (3) were prepared by reacting 5-(3-pyridyl)-1,3,4-oxadiazole-2-thioacetic acid (HL) with corresponding metal acetate in DMF/CH3CN medium under solvothermal condition. The isolated complexes were characterized by elemental analysis and infrared spectroscopy. The X-ray crystallographic analysis revealed double strand structure of 1 and 2, and 3D framework of 3. The different structures of these complexes indicate that the configuration of the ligand and the reaction condition play a key role in self-assemble of complexes 13. Furthermore, photoluminescent properties of 1 and 2 were also studied in the solid state.
