Synthesis, characterization, and antimicrobial activities of some transition metal complexes with a tridentate dibasic Schiff base and bidentate 2,2 '-bipyridylamine

The mixed-ligand complexes of Cu(II), NI(II), Zn(II), Co(II), Fe(II), Mn(II ), and Cd(II) with 2,2 ' -bipyridylamine (Bipy-amine) and a Schiff base (H2 SB) were prepared and characterized on the basis of elemental analyses, mag netic measurements, infrared spectra, electronic spectra and thermogravimet ric analyses. An octahedral geometry has been assigned to all of the prepar ed complexes. The antimicrobial activities of the complexes were tested aga inst bacteria, yeast and fungi and the results are discussed.
