Temperature and salt effects of the kinetic reactions of substituted 2-pyridylmethylene-8-quinolyl iron (II) complexes as antimicrobial, anti-cancer and antioxidant agents with Cyanide ions
Kinetics of substitution reaction of three high spin pyridylmethylene-8-quinolyl iron (II) complexes by CN- ions are studied spectophotometrically in various ratios of aqueous-methanol binary mixtures at 298 ± 0.2 K. Kinetics of the substitution reaction follow the rate law (k2[CN−][complex])on applying of the conditions of the pseudo-first-order. Reactivity of the reaction was investigated in terms of organic ligand moiety and ... Read more

An alternative sequence of bioactive series, using novel Schiff base derivative (1-Quinolin-8-yliminomethyl-naphthalen-2-ol), was produced (HNQ). Elements analysis, molar conductivity, magnetic moment, IR, 1H NMR, UV-Vis, and TGA were used to define the chemical forms. As a result, an appropriate geometry has been proposed for each complex. The HNQ ligand functions as a tri-dentate _via_ NNO donors to the metal ions ... Read more
