Characterization and structural study of the complex of Al(III) with 2,4-dihydroxy-benzophenone. Ionic strength and solvent effects

Structural and spectroscopic study of 5,7-dihydroxy-flavone and its complex with aluminum

“…In order to determine the chelating capacity of metallic ions of simple flavonoids and benzophenones of biological interest, we recently studied the complexating reaction of 2-hydroxy-benzophenone and 2,4-dihydroxy-benzophenone with AlCl 3 [10][11][12]. In this work, we determine the stoichiometry of the complex formed between AlCl 3 and 5,7-dihydroxy-flavone in methanol, its equilibrium constant and molar absorptivity.…”

Solvatochromic Effect Studies on the Stability of Dioxovanadium(V) Complexes with Ethylene Glycol-bis(2-aminoethylether)-N,N,N′,N′-tetraacetic Acid in Different Water + Methanol Mixtures

“…Although several multiparameter equations have been proposed, the KAT equation seems to be the most widely applied multiparameter approach. A literature survey reveals that in spite of several papers about application of the KAT equation [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] there are no reports on the complexation of dioxovanadium(V) with ethylene glycol-bis(2-aminoethylether)-N,N,N′,N′-tetraacetic acid (EGTA) in different aqueous solutions of methanol by using the KAT equation. The present study deals with the aforementioned system to investigate the contribution of the KAT parameters.…”
