Preparation, Characterization, and Antimicrobial Activities of Some Mixed‐Ligand Complexes of Mn(II), Co(II), Ni(II), Cu(II), and Cd(II) with Monobasic Bidentate (ON) Schiff Base and Neutral Bidentate (NN) Ligands

Abstract

Complexes of Mn(II), Co(II), Ni(II), Cu(II), and Cd(II) with 3,5‐dibromosalicylidene‐p‐anisidene (HSB) and 2,2′‐bipyridylamine (bipyamine) or bis(benzylidene)ethylenediamine (benen) or bis(acetophenone) ethylenediamine (acphen) have been prepared. They were characterized by elemental analyses, magnetic measurements, electronic and infrared spectra. All the ligands, metal salts, and their complexes were screened for their antimicrobial activities against bacteria, yeast, and fungi and the results are discussed.
