In this paper, nanostructure of new 1D Pb(II) coordination polymers, [pb2 (C2Cl3O2)2(NO3)2 (Cl2H8N2)2] n were synthesized by a sonochemical method in different concentrations. Coordination polymers Lead (II) include a chain made of interlocking metal formed with ligands that are Cl3COO- and NO3-. The coordination geometry is based on a pentagonal–bipyramidal geometry defined by an N2O5 donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The new nanostructure was characterized by Scanning Electron Microscopy (SEM), IR spectroscopy, X-Ray powder Diffraction (XRD), and elemental analyses. The average size of the nanoparticles 80 nm. The concentration of  initial reagents effects on the size and morphology of nano-structured compound 1 have been studied and show that low concentrations of initial reagents decreased particle size and led to uniform nanoparticle morphology.
