Synthesis and Characterization of Copper(II)-Oxide Nanoparticles from Two Cu(II) Coordination Polymers

CuO nano particles were obtained by calcination of nano-sized  [Cu(C4H4O4)(bipy)(H2O)2].2H2O (1) and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) (2) which are two  Cu(II) coordination polymers. The two coordination polymers [Cu(C4H4O4)(bipy)(H2O)2].2H2O and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) were synthesized and characterized by Fourier transform infrared spectra (FT-IR spectroscopy), thermal gravimetric (TGA) and differential thermal analyses (DTA). CuO nano particles were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).The two coordination polymers obtained possessed nano sizes.
