Abstract:Two new lead(II) nitrate coordination polymers from ligand 1,2-di-(4-pyridyl)-ethylene (bpe), Pb2(μ-bpe)3(μ-NO3)2(NO3)2]n (1) and {Pb(μ-bpe)(μ-NO3)2(NO3)(H2O)]·(Hbpe)·0.5(bpe)}n (2), were synthesized. The compounds 1 and 2 were characterized by IR spectroscopy, elemental analyses and X-ray crystallography. The structures of 1 and 2 may be considered coordination polymers of lead(II) consisting of metallocyclic chains formed by bridging bpe ligands, making two- and one-dimensional array of Pb(NO3)2 and bpe, respectively. Pure phase PbO nano-particles were obtained by thermolyses of compounds 1-2 in oleic acid as surfactant at 180 and 200 °C under air atmosphere. The PbO nanoparticles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
