Abstract

Metal-organic coordination polymers are a class of organic–inorganic materials consists of metal ions linked together through multi-dentate organic ligands, to form a polymeric chain. These materials have received a great deal of attention in a wide range of different areassuch as catalysis, sensing, luminescence, separation and storage used . The new nano flowerPb(II) 1Dmetal-organic chain {[Pb(phen)(μ-CH3COO)]•(BF4)}n(1) (phen=1,10-phenanthroline) was synthesized by a sonochemical irradiation assisted method. The compound was characterized by scanning electron microscopy (SEM), elemental analysis, FT-IR spectroscopy, X-ray powder diffraction (XRPD) and single crystal X-ray analysis. The X-ray analysis reveals a 1Dchain metal-organic coordination polymer structure for 1 thatis further extended into a 3D supramolecular structure by π-π and other labile interactions. The coordination number of the lead(II) ions is determined was abouteight, PbF2N2O4. The lead oxide nanoparticles were prepared at 180 °C by the thermolysis of 1. The average diameter of the nanoparticles to be 27 nm. The size and morphology of the prepared PbO samples were further observed using SEM.
