Syntheses and characterization of nano-sized lead (II) coordination compound with bitiazole ligand as precursor of nano particles of PbO

Nanoparticles of a two-dimensional coordination compound, [Pb(DADMBTZ)2(NO3) (CH3COO)]n (1),have been synthesized by a sonochemical process and characterized by scanning electron microscopy, X-ray powderdiffraction, IR spectroscopy and elemental analyses. The thermal stability of compound 1 both its bulk and nano-size hasbeen studied by thermal gravimetric (TG) and differential thermal (DTA) analyses and compared each other. The role ofpower ultrasound irradiation on size and morphology of nano-structured compound 1, has been studied. Calcination ofthe single crystals and nano-sized compound 1 at 400°C under air atmosphere yields mixture of PbO nanoparticles.Results show that the size and morphology of the PbO nanoparticles are dependent upon the particles size of compound1. A decrease in the particle size of compound 1 leads to a decrease in the particles size of the PbO.
