Copper(II) complex of 3-cinnamalideneacetylacetone: Synthesis and characterisation

A bidentate ligand derived from cinnamaldehyde and acetylacetone and its copper(II) complex have been synthesized and characterized by elemental analysis, UV-Vis, IR, ESR and magnetic susceptibility measurements. Magnetic susceptibility measurements, ESR and electronic spectral data indicate the presence of six coordinated Cu(II) ion. The ligand and complex are tested for antibacterial activity against Pseudomonas aeroginosa. They are found to show the antibacterial activity.
