Two pairs of tri- and divalent complex cations [Co(en)<SUB>3</SUB>]<SUP>3+</SUP>, [Ni(en)<SUB>3</SUB>]<SUP>2+</SUP> and [Co(phen)<SUB>3</SUB>]<SUP>3+</SUP>, [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP> were chromatographed through the SP-Sephadex cation-exchange column using various concentrations of aqueous KBr and K<SUB>2</SUB>SO<SUB>4</SUB> solutions as eluent, and the inversion of the elution order was observed for the pair of the phen complexes when eluted with KBr and for that of the en complexes when eluted with K<SUB>2</SUB>SO<SUB>4</SUB>.
