Synthesis, physicochemical characteristics, and biocidal activity of some transition metal mixed-ligand complexes with bidentate (NO and NN) Schiff bases

Mixed-ligand complexes of the type [M(SB)2acphen], where M = Mn(II), Co(II), Ni(II), Cu(II), and Cd(II), HSB = 3,5- dibromosalicylideneaniline, and acphen = bis(acetophenone)ethylenediamine, have been prepared and characterized on the basis of elemental analyses, magnetic measurements, thermogravimetry, and infrared and electronic absorption spectroscopy. All the mixed-ligand complexes exhibit an octahedral geometry. The mixed-ligand complexes show antimicrobial activities against bacteria, yeast, and fungi. © 2007 Springer Science+Business Media, Inc.
