Copper complexes of 4-dihydroxyacetophenone-2-iminoethanethiol)(DAET),
2,4-dihydroxybenzophenone- 2-iminoethanethiol (DBET), 2,4-dihydroxyac
etophenone-2-iminobenzenethiol (DABT) and 2,4-dihydroxybenzophenone-2-
iminobenzene (DBBT) have been synthesized and characterized by element
al analysis, conductivity, magnetic susceptibility measurements, IR, e
lectronic and ESR spectral data The molar conductivity data show them
to be non-electrolytes. The tridentate nature of the ligands is inferr
ed from IR spectral studies. The electronic spectral data suggest plan
ar geometry for all the complexes. Various ESR parameters have been ca
lculated. The antibacterial activities of the ligands and their copper
complexes have been screened in vitro against the organisms Escherchi
a coli (E.C), Bacillus (B) and Pseudomonas aeruginosa (P.S). It is obs
erved that the coordination of metal ions has pronounced effect on the
bacterial activities of the ligands.
