Abstract

Two new vanadium complexes, [VO(L1)2] (1) and [V2O2(μ-O)2(L2)2] (2), where L1 is 2-(cyclohexyliminimethyl)-4,6-difluorophenolate, L2 is 2,4-difluoro-6-[(2-isopropylaminoethylimino)methyl]phenolate, have been synthesized and characterized by elemental analysis, FT-IR and UV-Vis spectra, and single crystal X-ray determination. The V atom in complex 1 is in a coordination between trigonal bipyramidal and square pyramidal, and that in complex 2 is in octahedral coordination. The antibacterial activity of the compounds against various bacteria was assayed. The fluoro-substituted groups play an essential role in the biological process.
