A new multidentate ligand 2-(5-fluoro-2-methyl-lH-inden-3-yl)-N'-((3-methyl-5-oxo-l-phenyl- 4,5dihydro-lH-pyrazol-4- yl)(phenyl) methylene)acetohydrazide i.e. FIMPPH have been derived in good yield by the reaction of 4-benzoyl-3-methyl-l-phenylpyrazol-5- one with 2-(5-fluoro-2-methyl-lH-inden-3-yl)acetohydrazide. It has been employed for the synthesis of the metal complexes with the transition metal ions viz. Fe2+, Co2+, Ni2+ and Zn2+. Both the ligand FIMPPH and its metal complexes are studied for the antimicrobial activity.
