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)22- 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 SO42-.
