Synthesis, characterization, Crystal structure Electrochemical, Solvatochromic and Biological investigation of Novel N4 and N3 type Cu(II) Schiff base complexes

Abstract

In the present study, three novel Cu(II) Schiff base complexes of [CuL](ClO4)2, [CuL’Cl2] and [CuL’(NO3)2] (L: N, N’-bis(2-pyridinylmethylene)-1,2-diphenylethylenediamine and L’: N-(2-pyridinylmethylene)-1,2-diphenylethylenediamine ) were synthesized and then characterized using infrared spectroscopy, elemental analysis, conductivity measurements and X-ray crystallography. The crystal structure of [CuL’(NO3)2] and [CuL’Cl2] complexes were determined by X-ray crystallography. We could not obtain suitable single crystal for [CuL](ClO4)2. The complexes were assessed for thermal, electrochemical and biological behaviors and the electronic absorption. Among the complexes, only the [CuL](ClO4)2 complex showed solvatochromic properties in various solvents. The antibacterial activities of these complexes were evaluated in Muller-Hinton broth against Staphylococcus aureus, Escherichia coli and Enterococcus faecalis using serial dilution technique at the concentrations of 2 to 0.0625 mg/ml. The data demonstrated that the complexes were bacteriostatic agents that inhibited the bacterial growth, but had no bactericidal property
