A new 3D coordination polymer based on 2,6-dimethylpyridine-3,5-dicarboxylic acid and 4,4'-bipyridine mixed ligands

摘要

A new porous coordination polymer, namely [Zn2(MPDC)2(4,4'-Bpy)(DMF)]-(DMF) 1 (H2MPDC = 2,6-dimemylpyridine-3,5-dicarboxyIic acid, 4,4'-Bpy = 4,4'-bipyridine, DMF = N,N'-dimethylformamide), has been successfully synthesized under solvothermai conditions. The result of crystal structural analysis indicates that compound 1 shows a three-dimensional (3D) network framework with 1-D channels along the a-axis. From the view of topology, the framework of 1 can be represented as a 2,3,4-connected net Further characterization of compound 1 was performed by X-ray powder diffractioa thermal gravimetric analyses, and infrared spectra. In addition, compound 1 exhibits strong photoluminescent emissions in the solid state at room temperature.
