    Sonochemical synthesis and characterization of the new plate-shaped lead(II)-iodo coordination polymer: a precursor to produce a pure phase nano-sized lead(II) oxide
    (Springer Verlag, 2012) Mirtamizdoust, B.; Shaabani, B.; Khandar, A.; Pourradi, H.; Abbasityula, Y.; Goudarziafshar, H.; Viterbo, D.; Croce, G.; Hojati-Talemi, P.
    Preparation of plate-shaped nanostructures of a new 1D polymeric lead(II) complex containing the Pb2-(μ-I)2 motif, [Pb(neo)I2] n ,(1) where neo is the abbreviation of neocuproine, using a sonochemical method is described. The new coordination polymer is characterized by scanning electron microscopy, X-ray diffraction (XRD), elemental analysis and infrared spectroscopy. The single crystalline material is obtained using a heat gradient applied to a solution of the reagents. Single-crystal XRD analysis indicates that a coordination number of six for PbII ions, (i.e., PbN2I4) with an asymmetrical coordination sphere and “stereo-chemically active” electron lone pairs. They also show that the chains interact with each other through π–π stacking interactions creating a 3D framework. PbO nanoparticles are obtained by thermolysis of 1 at 180 °C with oleic acid as a surfactant. Scanning electron microscopy confirms formation of PbO particles with a size of ~25 nm.
