Abstrakty

Neutral complexes of Cu(II), Ni(II), Co(II), Mn(II), VO(II) and Zn(II) have been synthesized from the Schiff base derived from benzil and 2-aminobenzyl alcohol. The structural features have been arrived from their microanalytical, IR, UV-Vis, 1H NMR, Mass and ESR spectral data. All of the complexes exhibit square-planar geometry except the Mn(II) and VO(II) complexes. The Mn(II) chelate shows an octahedral environment and the VO(II) chelate exists in a square-pyramidal geometry. The monomeric and non-electrolytic nature of the complexes is evidenced by their magnetic susceptibility and low conductance data. The cyclic voltammogram of copper complex in acetonitrile solution shows two quasi reversible peaks for the Cu(II)/Cu(III) and Cu(II)/Cu(I) couples. The X-band ESR spectra of the Cu(II) and VO(II) complexes in DMSO at 300 and 77 K were recorded and their salient features are reported. The biological activity of the metal chelates against the bacteria Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, Salmonella typhi, Pseudomonas aeruginosa and Shigella flexneri are also reported. Most of the complexes have higher activity than that of the free Schiff base and the control.
