Some acylhydroxypyrazole acylhydrazones, e.g., I (R = pentyl, Pr), and their 3d transition metal(II) complexes were synthesized. The ligands and their 3d transition metal complexes were characterized by elemental anal., molar conductance, magnetic susceptibility measurements and spectroscopic methods. The ligands behaved as mono-anion ONO or ONS donor mols. Microanal., electronic spectral and magnetic measurements showed the metal complexes as ML2 type. All the synthesized compounds were screened for their in vitro antimicrobial activity against some gram pos. and gram neg. clin. bacterial strains. Antimicrobial activity test results showed that the metallic derivatives are more active against the bacterial strains than the imines.
