The Bis(4-methoxy-2-hydroxybenzophenone) copper(II) Complex Used as a New Precursor for Preparation of CuO Nanoparticles

Abstract

In this study, the reaction of 4-methoxy-2-hydroxybenzophenone (HL) with copper(II) nitrate three hydrate in a 1:2 molar ratio in methanol as solvent resulted in the formation of the complex CuL2. In order to prepare a suitable single crystal, slow evaporation technique was used, while for preparing complex nanoparticles, assisted ultrasound was used. Crystal structure of CuL2 was determined by single crystal X-ray diffraction. A square-planar geometry was found for CuL2. Finally, the complex was calcinated at 600 °C for 2.5 h. The final residue was CuO nanoparticles which were characterized by SEM and XRD. There is no peak for impurity in the XRD pattern.
