Preparation, characterization and antimicrobial properties of some palladium and platinum complexes with active Schiff base ligands

The synthetic. spectroscopic and biological studies of some palladium and platinum complexes derived from 5-methyl1.3-dihydro-3-[2-(phenyl)ethylidene ]-2H-indol-2-one-hydrazinecarbothioamidei( L' H) and 5-methyl-I.3-dihydro-3-[2(phenyl)ethylidene]-2H-indol-2-one-hydrazinecarboxamide(L2H) are reported here. These complexes have been characterized on the basis of elemental analysis. molecular weight determinations and spectral studies including JR. 'H NMR and electronic spectra. The resulting coloured products are monomeric in nature. On the basis of the above studies. square planar geometry has been proposed for the resulting complexes. Both the ligands and their complexes have been screened for their fungicidal and bactericidal activities and the results indicate that they exhibit significant antimicrobial properties .
