• Additional elution experiments for confirming the fact that the trans ions of the diacidotetrammine-type complexes are always eluted faster than the corresponding cis ions have been performed by using several diacido-type complexes which are relatively unstable. By comparing the elution maxima for the whole complex ions which have been used to date, the relative adsorbabilities of the isomeric ions on a cation exchanger have been predicted as follows:<BR>For the trans ions,<BR> [Co en<SUB>2</SUB>(NCS)<SUB>2</SUB>]<SUP>+</SUP><[Co en<SUB>2</SUB>(NO<SUB>2</SUB>)<SUB>2</SUB>]<SUP>+</SUP>\simeq<BR> [Co en<SUB>2</SUB>Br<SUB>2</SUB>]<SUP>+</SUP><[Co en<SUB>2</SUB>Cl<SUB>2</SUB>]<SUP>+</SUP>\simeq<BR> [Co en<SUB>2</SUB>NO<SUB>2</SUB>Cl]<SUP>+</SUP><[Co(NH<SUB>3</SUB>)<SUB>4</SUB>(NO<SUB>2</SUB>)<SUB>2</SUB>]<SUP>+</SUP><<BR> [Co en(NH<SUB>3</SUB>)<SUB>2</SUB>Cl<SUB>2</SUB>]<SUP>+</SUP><BR>For the cis ions,<BR> [Co en<SUB>2</SUB>Cl<SUB>2</SUB>]<SUP>+</SUP><[Co en<SUB>2</SUB>(NCS)<SUB>2</SUB>]<SUP>+</SUP><<BR> [Co en(NH<SUB>3</SUB>)<SUB>2</SUB>Cl<SUB>2</SUB>]<SUP>+</SUP>\simeq[Co en<SUB>2</SUB>NO<SUB>2</SUB>Cl]<SUP>+</SUP><<BR> [Co en<SUB>2</SUB>(NO<SUB>2</SUB>)<SUB>2</SUB>]<SUP>+</SUP><[Co(NH<SUB>3</SUB>)<SUB>4</SUB>(NO<SUB>2</SUB>)<SUB>2</SUB>]<SUP>+</SUP><BR>A part of the present work was supported by a grant-in-aid from the Ministry of Education.
