Synthesis, Crystal Structure and Fluorescent Property of a Novel Cd(II) Coordination Polymer based on Nitrogen-Containing Ligands

A novel Cadmium(II) coordination polymer, namely {[Cd(L)(bpmh)_0.5(DMA)(H₂O)]}_n (CP 1), has been successfully synthesized under solvothermal conditions using H₂L (5-(1-oxoisoindion-2-yl)isophthalic acid) and bpmh ((1E,2E)-1,2-bis(pyridine-4-ylmethylene)hydrazine) ligand. The CP 1 is well described by single-crystal X-ray diffraction, PXRD, FT-IR, TGA and solid-state fluorescence properties. X-ray single crystal diffraction analysis shows that CP 1 crystallizes in the P-1 space group, and possesses 1D ladder chains, which were further connected by hydrogen bonding interactions to form 3D supramolecular architecture. Results of the property studies showed that we successfully synthesized a pure phase fluorescent material with good thermal stability and has potential applications for the development of future fluorescent materials.(II)
