Synthesis, characterization and antifungal studies of metal complexes of benzoyl- and salicylylhydrazones of omega-bromoacetoacetanilide

Ten new transition metal complexes of benzoylhydrazone (L-1 H-2) and salicylylhydrazone (L-2 H-3) of omega-bromoacetoacetanilide have been synthesized. These complexes were characterized mainly by elemental analyses, molar conductance and magnetic susceptibility measurements along with electronic, infrared, and H-1 NMR spectral studies. Antifungal tests of the ligands and their Mn( II), Co( II), Ni( II), and Cu( II) complexes were also carried out. The antifungal activities of the complexes were greater than those of the ligands.
