Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The crystallinity of these compounds were studied by Powder X-ray diffraction (XRD). CdO nanostructures were obtained by direct calcinations of nano polymers at 400 oC. The cadmium (II) oxidenano-particles were characterized by Powder X-ray diffraction (XRD) and scanning electron microscopy (SEM).
