Nanoparticles of a one-dimensional coordination polymer [Pb(L)(mu(2)-I)](n) (1), (L = 1H-1,2,4-triazole3- carboxylate), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. The thermal stability of compound 1 both its bulk and nano-size has been studied by thermal gravimetric (TG) and compared each other. Concentration of initial reagents effects and the role of power ultrasound irradiation on size and morphology of nano-structured compound 1 have been studied and show that low concentrations of initial reagents and also high power of ultrasound irradiation decreased particles size and leaded to uniform nanoparticles morphology. PbO nano-structures were simply synthesized by solid-state transformation of compound 1 at 630 degrees C under air atmosphere whereas thermal decomposition of compound 1 in oleic acid as surfactant at 200 degrees C yield PbI2 nanoparticles.
