A novel polymeric Pb(11) complex containing three different ligands [Pb(mu-4 4'-bipy)(mu-OAc)(hfacac)](n) (1) (4 4'-bipy = 4 4' bipyridine OAc(-) = acetate and hfacac(-) = hexafluoroacetylacetonate) has been synthesized and characterized The single-crystal X-ray data showed that the coordination number in Pb(11) ion is eight with holodirected geometry The structure may be considered as a coordination polymer of lead(II) consisting of linear double chains formed by bridging 4 4' bipy ligands and by connecting the acetate-bridged centrosymmetric (Pb(2)(OAc)(2))(2+) nodes The self-assembly of compound 1 is likely to be caused by C-H F-C and pi-pi stacking interactions The thermal stability of compound 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA) Nano sized MO was obtained by thermolyses of compound 1 in oleic acid at 290 C under air atmosphere The nano-materials were characterized by scanning electron microscopy X-ray powder diffraction (XRD) and IR spectroscopy The thermal stability of nano-structure MO was studied by thermal gr
