Abstract:

The sulfur-nitrogen donor ligand, 1-acetylferrocenehydrazinecarbothioamide (L1H) and oxygen-nitrogen donor ligand, 1-acetylferrocenehydrazinecarboxamide (L2H) have been synthesized by condensation of 1-acetylferrocene with corresponding hydrazinecarbothioamide and hydrazinecarboxamide, respectively. The structure determination of palladium(II) and platinum(II) complexes was performed by elemental analysis, melting point determinations, conductivity measurements, molecular weight determinations, IR, 1H NMR and UV spectral studies. Based on these studies the square planar environment around the metal atoms has been proposed. Studies were also conducted to assess the comparative growth- inhibiting potential of the synthesized complexes and the azomethines against a variety of fungal and bacterial strains.

Keywords: Antimicrobial activity; hydrazinecarbothioamide and hydrazinecarboxamide; palladium(II) and Platinum(II) complexes; spectral studies
