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.
杂环酮亚胺、5-硝基-3-(吲哚啉-2-酮)肼基硫代甲酰胺(L1H)、5-硝基-3-(吲哚啉-2-酮)肼基甲酰胺(L2H)、6-硝基-3-(吲哚啉-2-酮)肼基硫代甲酰胺(L3H)、和 6-硝基-3-(吲哚啉-2-酮)肼甲酰胺(L4H)是由硫代氨基脲和盐酸氨基脲(在乙酸钠存在下)在乙醇中与相应的酮缩合制备的。二氧二钼(VI)络合物和氧钒(V)络合物是通过将摩尔比为 1:2 的二氧双(2,4-戊二酸)钼(VI)和摩尔比为 1:1 和 1:2 的氧三氯化钒与单碱基双齿酮亚胺混合而制备的。通过元素分析、电导测量和光谱研究(包括红外光谱、1H NMR 光谱和紫外光谱),对所得复合物进行了表征。这些酮亚胺及其相应的金属复合物已在一些病原细菌和真菌上进行了测试,以评估它们在不同浓度下的生长抑制效力。
