P. aeruginosa, E. coli, and E. cloacae, and weak activity
against B. subtilis and S. aureus. In general, the activi-
ties of the two complexes are much effective than the
free Schiff bases. The only exception is complex II,
which show no activity against P. aeruginosa. Com-
plexes I and II have similar activities against all the
bacteria, indicating the central benzene ring of the
Schiff base ligand is not an essential factor in the anti-
bacterial processes. Such an enhanced activity of the
complexes than the free Schiff base can be explained
on the basis of Overtone’s concept and Tweedy’s che-
lation theory [23]. According to Overtone’s concept of
cell permeability, the lipid membrane that surrounds
the cell favors the passage of only lipid soluble materi-
als due to which liposolubility is an important factor
that controls antimicrobial activity. On chelation, the
