SYNTHESIS, SPECTROSCOPIC STUDIES, AND ANTIMICROBIAL ACTIVITY OF Mn(II), Co(II), Ni(II), Cu(II), AND Cd(II) COMPLEXES WITH BIDENTATE SCHIFF BASES AND 2,2′-BIPYRIDYLAMINE

A few mixed-ligand complexes of the types [M(SB1)2Bipy-amine] and [M(SB2)2Bipy-amine], (M=Mn(II), Co(II), Ni(II), Cu(II) and Cd(II), HSB1 =5-chlorosalicylideneaniline, HSB2 =5-bromosalicylideneaniline and Bipy-amine=2,2′-bipyridylamine) have been prepared and characterized on the basis of elemental analyses, magnetic measurements, infrared spectra and electronic spectra. The mixed-ligand complexes shows antimicrobial activities against bacteria, yeast sand fungi.
