title: Sonochemical synthesis of nanoscale mixed-ligands lead(II) coordination polymers as precursors for preparation of Pb(2)(SO(4))O and PbO nanoparticles; thermal, structural and X-ray powder diffraction studies.
abstract: Nano-structures of two new Pb(II) two-dimensional coordination polymers, [Pb(micro-4-pyc)(micro-NCS)(micro-H(2)O)](n) (1) and [Pb(micro-4-pyc)(micro-N(3))(micro-H(2)O)](n) (2), 4-Hpyc=4-pyridinecarboxylic acid were synthesized by a sonochemical method. The new nano-structures were characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and elemental analyses. Compounds 1 and 2 were structurally characterized by single crystal X-ray diffraction and consist of two-dimensional polymeric units. The thermal stability of compounds 1 and 2 were studied by thermal gravimetric and differential thermal analyses and compared. Pb(2)(SO(4))O and PbO nanoparticles were obtained by calcination of the nano-structures of compounds 1 and 2 at 600 degrees C, respectively.
