were obtained, respectively. The complexes were characterized by IR and UV–vis. spectroscopy. The visible spectra of the complexes revealed the square pyramidal geometry around the central Cu 2+ ions. The molecular structures of the complexes 2 , 3 , 4 and 5 were determined by single crystal X-ray crystallography. This study revealed the dinuclear nature of the complexes and showed that the Cu(II) centers
