Tetranuclear Copper (II) schiff base complexes as new precursor for synthesis of CuO nanoparticles by solid-state thermal decomposition

In this paper, we used tetranuclear copper (II) Schiff base complexes, [Cu4 (?-sal2hn) (?-N3)2(N3)2] (1) and [Cu4 (?-salophen) (?1, 1-N3)2(N3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of CuO nanoparticles. The crystallinity, purity and morphology of the CuO nanoparticles were characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM).
