Abstract: Reaction of the ligand precursor, 4-benzyl-oxybenzoylhydrazine (1) with benzaldehyde and substituted ben-zaldehydes (e.g., 4-methoxybenzaldehyde, 4-chlorobenzaldehyde, 4-bromobenzaldehyde, 4-nitrobenzaldehyde, 4-methyl-benzaldehyde, 4-ethylbenzaldehyde) with nickel(II) acetate yields the complexes bis[N-4-substituted benzylidene(4-benzyloxy) benzoyl-hydrazinato]nickel(II) 3-9, respectively. The complexa-tion proceeds via the intermediate ligand formation (2), not the template method. Complexes having the electron withdrawing groups of the benzylidene moiety (=CHC₆H₄X) are more soluble than having the electron donation groups. Among the compounds, only 3, 4 and 8-11 show activity against the pathogenic bacteria (E. coli, S. dysentria, B. subtilies, St.-haemolytica), while other compounds 5-7 and 12 do not show any activity. The electron donating group (X = H, OCH₃, CH₃, C₂H₅) of the benzylidene moiety (=CHC₆H₄X) may be responsible for the activity of the compounds.
