Synthesis,crystal structure and luminescent properties of a new 3D coordination polymer constructed by Cd(II)with 4,4'-oxybis(benzoate)and 4,4'-bipyridine

摘要

A new Cd(II)coordination polymer,[Cd(bpy)(oba)]_n(1)(H2oba=4,4'-oxybis(benzoic acid);bpy=4,4'-bipyridine)has been synthesized under the hydrothermal conditions and structurally characterized by elemental analysis,IR spectrum and single crystal X-ray diffraction.X-ray diffraction analysis reveals that 1 features an interesting 3D framework with wavelike[Cd2(oba)2]_n ribbons linked by 4,4'-bpy bridges.The oba ligand adopts chelating and chelating/bridging coordination modes.1 displays strong fluorescent emission in the solid state at room temperature.
