Nano-structured of new lead(II)coordination polymer, [PbBr2(C9H15N5O)]n (1), {C9H15N5O = minoxidil = (2,4-diamino-6-piperidine-1-yl)pyrimidine N-oxide} has been synthesized by the reaction of lead(II) acetate, KBr and minoxidil ligand in methanol by sonochemical method. The nanosized PbOHBr and PbO were prepared from nano-structured [PbBr2(C9H15N5O)]n by hydrothermal reaction in authoclave and calcinations under nitrogen, respectively. The structure of 1 was studied by elemental analysis, FTIR spectroscopy, X-ray powder diffraction (XRD). Nano-structures were characterized by XRD, scaning electron microscopy (SEM) and elemental analysis. Thermal stability of 1 at bulk and nanosized were studied and compared with each other.
