Abstract

Crystalline and nano-structure of a new Pb(II) coordination polymer, [Pb(NO2)(2-quc)]n (1), {Hquc = 2-quinoline carboxylic acid} is synthesized via heat gradient and sonochemical methods, respectively. The newly synthesized structures are characterized by scanning electron microscopy (SEM), X- ray powder diffraction (XRD), IR and 1HNMR spectroscopies, elemental analyses and single crystal X-ray diffraction is used to understand the exact structure of the crystalline 1. Thermal stability of nano and bulk samples of compound 1 are studied and compared through thermal gravimetric and differential thermal analyses. PbO nanoparticles are then produced by calcination of the nano-structure of compound 1 at 600 °C. The obtained PbO is characterized by XRD and SEM analyses.
