Complex formation of beryllium sulfate in mixtures of water and dimethylformamide

Abstract

The complex formation of BeSO₄ in mixtures of water and dimethylformamide (dmf) has been studied by using conductivity and kinetic measurements. In these solutions the complex Be(SO₄)₂^2- is shown to exist together with the outer- and inner-sphere complex of BeSO₄. The rate of substitution depends on the composition of the solvatomer Be(H₂0)_I(dmf)_4-I²⁺ which reacts with the sulfate ion and on the kind of solvating molecule which is substituted by the ligand SO₄^2-.
