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 oC 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.
