Abstract

In this study, a new complex consisting of iron metal coordination in a binary oxidation state, synthesized with mixed ligands, which are imidazole and 1,10-phenanthroline. The absorbance measurement at the maximum wavelength of the complex with a concentration of 0.001M was run at 504 nm. For the new complex, the optimum conditions were studied and it was found that it is stable over 3 days at pH 6 at temperature range of (20-80°C). The complex conductivity was 99.7µs/L and it was found that the complex decomposed after 208°C). The formation ratio was 1:2:1 iron: imidazole: 1,10-phenanthroline, respectively. A calibration curve was constructed to determine the limit of detection which was 0.20 mg/L. This study was applied to measure the number of iron ions in the ferrous sulfate tablet and the result was very close to the standard amount of ferrous in tablet sample. The complex formation was detected by using different spectroscopic techniques such as FT-IR and 1HNMR. On the other hand, the antibacterial activity and the antioxidant activity of the complex were studied.
