In the present study, three novel Cu(ii) Schiff base complexes [CuL](ClO 4 ) 2 , [CuL′Cl 2 ] and [CuL′(NO 3 ) 2 ] (L: N,N′-bis(2-pyridinylmethylene)-1,2-diphenylethylenediamine and L′: N-(2-pyridinylmethylene)-1,2-diphenylethylenediamine) were synthesized and characterized using infrared spectroscopy, elemental analysis, conductivity measurements and X-ray crystallography. The crystal structure of the [CuL′(NO 3 ) 2 ] and [CuL′Cl 2 ] complexes were determined by X-ray crystallography. However, suitable single crystals for [CuL](ClO 4 ) 2 could not be obtained. The complexes were assessed to determine their thermal, electrochemical and biological behaviors and electronic absorption. Among the complexes, only the [CuL](ClO 4 ) 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 the serial dilution technique at concentrations ranging from 2 to 0.0625 mg mL −1 . The data demonstrates that the complexes were bacteriostatic agents that inhibit bacterial growth, but had no bactericidal properties. [ABSTRACT FROM AUTHOR]
