Abstract: | Heterocyclic ketimines, 5-nitro-3-(indolin-2-one)hydrazinecarbothioamide (L1H), 5-nitro-3-(indolin-2-one)hydrazinecarboxamide (L2H), 6-nitro-3-(indolin-2-one)hydrazinecarbo-thioamide (L3H), and 6-nitro-3-(indolin-2-one) hydrazinecarboxamide (L4H), were prepared by the condensation of thiosemicarbazide and semicarbazide hydrochloride (in the presence of sodium acetate)
in ethanol with the respective ketones. The dioxomolybdenum(VI) complexes and oxovanadium(V) complexes have been prepared
by mixing dioxobis(2,4-pentanedinato)molybdenum(VI) in 1: 2 molar ratios and vanadium oxytrichloride in 1: 1 and 1: 2 molar
ratios with monobasic bidentate ketimines. The resulting complexes have been characterized by elemental analysis, conductance
measurements, and spectral studies, including IR, 1H NMR, and UV spectra. The ketimines and their corresponding metal complexes have been tested on a number of pathogenic bacteria
and fungi in order to assess their growth inhibition potency at different concentrations.
