SYNTHESES, CHARACTERIZATION, AND ANTIBACTERIAL PROPERTIES OF COPPER(II) COMPLEXES DERIVED FROM FLUORO-CONTAINING SCHIFF BASES
2021
A centrosymmetric dinuclear copper(II) complex [Cu2(La)2] (1) and two mononuclear copper(II) complexes [Cu(Lb)2] (2) and [Cu(Lc)2] (3), where La, Lb, and Lc are deprotonated anionic forms of 2-((cyclopropylimino)methyl)-4,6-difluorophenol (HLa), 2-((cyclohexylimino)methyl)-4,6-difluorophenol (HLb) and 2,4-difluoro-6-((2-hydroxyethylimino)methyl)phenol (HLc), respectively, are prepared and characterized by elemental analyses, IR and UV-Vis spectra, and single crystal X-ray diffraction. The Cu atoms in complex 1 are in a square pyramidal coordination, while those in complexes 2 and 3 are in a square planar coordination. The complexes exhibit interesting antibacterial activities against P. aeruginosa, S. typhi, and S. aureus.
