Resumen
The interaction of the oxidovanadium(IV) cation with the sodium salt of prephenic acid was investigated by electron absorption and electronic paramagnetic resonance spectroscopies in aqueous solution at different pH values. The study allows to demonstrate once more the effectiveness of oxidovanadium(IV) to interact with carboxylate groups. The most probable binding modes of the solution complexes were determined by EPR method. Two main coordination environments around the metal center were established: one includes four-carboxylate moieties and the other the set probably involves alkoxide and hydroxide groups
