Abstract [en]

The aqueous gallium(III)-acetate system was studied in 0.6 M Na(Cl) at 25 °C using a multi-technique approach, including potentiometry, IR spectroscopy, EXAFS spectroscopy and molecular orbital calculations. The potentiometric data were satisfactorily explained by a model which includes one mononuclear and one binuclear complex. The corresponding equilibrium constants defined according to the reactionsGa3++ HAc GaAc2++ H+2Ga3++ HAc + 2H2O Ga2(OH)2Ac3++ 3H+are log –1,1,1=–2.08 ± 0.09 and log –3,2,1=–5.65 ± 0.06, respectively. The latter complex has a stoichiometry identical to that previously identified in the aluminium(III)-acetate system. Also in agreement with this system, the IR and EXAFS data strongly indicates that this complex consists of two edge-sharing Ga octahedra bridged with an acetate ion, and should be formulated [Ga2(µ-OH)2(µ-O2CCH3)]3+. This interpretation is further supported by the molcular orbital calculations.
