Water soluble dicationic copper(II) complexes of general formula [Cu(dien)(NN)]Br2 [dien = diethelenetriamineand NN is diamines] were made available in good yield under ultrasonic mode.
The reaction was monitored by both FT-IR and UV-vis spectroscopy. The 3D structure was solved by X-ray single crystal diffraction. The solvatochromism phenomena of such complexes is recorded in several types of solvents. These complexes were spectrally and thermally characterized. The complexes showed higher antibacterial activity against several types of bacteria depending on their structures geometry.
