Synthesis, Structure and Luminescent Property of a 2D Cd(Ⅱ) Coordination Polymer Based on Mixed-ligands of 1,3-Bis(imidazol)propane and Pyridine-3,5-dicarboxylic Acid
摘要:
A new Cd(Ⅱ) coordination polymer, namely, [Cd(1,3-bip)(3,5-pdc)]n (1,3-bip=1,3-bis(imidazol)propane and 3,5-pdc=pyridine-3,5-dicarboxylic acid) has been synthesized under hydrothermal conditions. Compound 1 was characterized by infrared spectrum, elemental analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group P21/c with a=1.40178(7), b=1.72502(12), c=1.41635(6) nm, β=92.653(4)°, V=3.4212(3) nm3, Z=4, C16H15CdN5O4, Mr=453.73, Dc=1.762 g/cm3, F(000)=1808, μ=1.310 mm-1, R=0.0899 and wR=0.1945. In compound 1, each 3,5-pdc ligand links three Cd(Ⅱ) ions and each Cd(Ⅱ) attaches to bip ligands to form a complicated 2D double-layer structure. In addition, the thermal stability and luminescent property of 1 have been studied in the solid state at room temperature.
