the bis(4-methoxy-2-hydroxybenzophenone) copper(ii) complex used as a new precursor for preparation of cuo nanoparticles

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.
