title: Sonochemical synthesis of two new copper(II) complexes with azo ligands derived from anthranilic acid and β-naphtol.
abstract: Nanostructures of two new copper(II) complexes, (CuL1), 0.5EtOH. 1.5H2O (1), [H2L1=5-(4-Carboxy phenyl azo) anthranilic acid], (Cu(L2)2) (2), [HL2=1-(4-Carboxy phenyl azo) 2-naphtol] have been synthesized by the reaction of H2L1 and HL2 with Cu(OAc)2 · H2O through sonochemical process. Calcination of the nano-sized compounds 1-2 yield CuO nanoparticles at 550-450°C under air atmosphere. Metallic copper nanoparticles were prepared by direct calcination of compound 2 in surfactant at 180°C. These nanostructures were characterized by X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM). Thermal stability of compounds 1-2 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA).
