The influence of the medium and the substitution pattern on the complexing abilities of some hydroxyflavones: a spectroscopic and theoretical treatment
A series of hydroxyflavones, luteolin, morin and qurcetin, widely occurring in nature, have been used as model compounds for the study of the influence of the medium and the substitution patterns on the complexation abilities of these multi-site ligands towards Mg (II). The chelating powers of the investigated compounds have been compared in different media, pure methanol, and pure ethanol and in these alcohols containing AcO- . Electronic absorption spectroscopy was performed to characterize the stoichiometry and stability of the complexes formed.Semi empirical in vacuo calculations, performed in the AM1 parameterization, enabled the determination of the structural features of free compounds as well as complex structural modifications caused by Mg (II) ions.
