Synthesis of PbO nano-particles from a new one-dimensional lead(II) coordination polymer precursor
MetadataShow full item record
A new Pb(II) one-dimensional coordination polymer, [Pb(mu-NO2)(mu-pyc)(H2O)](n) (1). Hpyc = 2-pyridine-carboxylic acid] was prepared and characterized by elemental analyses, powder XRD diffraction and IR spectroscopy. Compound 1 was structurally characterized by single-crystal X-ray diffraction and one-dimensional coordination polymer with coordination environment of PbNO6. The thermal stability of compound 1 showed that compound 1 decomposes at 110-500 degrees C and the final product is PbO. This polymeric precursor has been used to make PbO nano-particles using two different surfactants. The new nano-structure was characterized by scanning electron microscopy and X-ray powder diffraction. This study demonstrates that the coordination polymers may be suitable precursors for the preparation of nanoscale materials. (C) 2010 Elsevier B.V. All rights reserved.
