Polymer 1 is synthesized in methanol by sonochemical and hydrothermal methods from lead(II) acetate, KBr and the minoxidil ligand. The crystal structure of [PbBr2(C9H15N5O)](n) indicates a syndiotactic coordination polymer. The Pb(II) atom lies on a mirror plane; the mirror plane is perpendicular to the pyrimidine ring bisecting the piperidine ring. N-H center dot center dot center dot O intramolecular and C-H center dot center dot center dot Br, N-H center dot center dot center dot N strong intermolecular interactions were observed. Micro-rods of PbO and nano-plates of PbOHBr were prepared by thermal decomposition of the nano-structured [PbBr2(C9H15N5O)](n) as a precursor. Characterization of the products was carried out using X-ray crystallography, elemental analysis, FTIR spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis and thermal analysis. The sonochemical method resulted in a significant reduction of reaction time, reaction temperature and particle sizes of the products.eninfo:eu-repo/semantics/closedAccessMinoxidilCoordination PolymerSonochemistryLead(Ii) Nano-StructuresArticle224837844WOS:0003052244000202-s2.0-8486264735310.1007/s10904-011-9648-6Q1Q3
