چکیده
|
Nanoparticles of two new coordination polymers, [pb(5,5′-dm-2,2′-bpy)cl2] n (1) and [pb(5,5′-dm-2,2′-bpy)br2] n (2), {5,5′-dm-2,2′-bpy = 5,5′-dimethyl-2,2′-bipyridine}, have been synthesized by ultrasonic assistance at different concentrations and characterized by scanning electron microscopy, x-ray powder diffraction, ir spectroscopy and elemental analyses. metal oxide nanoparticles were prepared from thermal decomposition of compounds 1 and 2 at 600 °c under air atmosphere. scanning electron microscopy images of the residue which are obtained from calcination of compounds 1, 2 show the formation of lead(ii) oxide nanoparticles with an average diameter of about 80 and 90 nm for compounds 1 and 2, respectively.
