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 (H2SB) were prepared and characterized on the basis of elemental analyses, magnetic measurements, infrared spectra, electronic spectra and thermogravimetric analyses. An octahedral geometry has been assigned to all of the prepared complexes. The antimicrobial activities of the complexes were tested against bacteria, yeast and fungi and the results are discussed.
