Prediction and correlations between the stability constants of mono- and polynuclear chromium(III) and iron(III) complexes

Correlations between the experimentally determined stability constants of mono- and polynuclear chromium(III) and iron(III) complexes are discussed. An equation to evaluate the stability constants of mono- and polynuclear chromium(III) complexes is obtained: \(\log \beta Cr_p^{3 + } (L_i )_{q_i } ] = 0.84\log \beta Fe_p^{3 + } (L_i )_{q_i } ]\) .
