The electrolytic conductances of bis(halogenoacetato)bis(ethylenediamine)cobalt(III) perchlorate, [Co(halac)<SUB>2</SUB>(en)<SUB>2</SUB>]ClO<SUB>4</SUB> where Hhalac=CH<SUB>3</SUB>CO<SUB>2</SUB>H, CH<SUB>2</SUB>ClCO<SUB>2</SUB>H, CHCl<SUB>2</SUB>CO<SUB>2</SUB>H, CCl<SUB>3</SUB>CO<SUB>2</SUB>H, and CF<SUB>3</SUB>CO<SUB>2</SUB>H were measured in water at 25°C. The equivalent conductances of the solutions (<I>c</I>=10<SUP>−3</SUP>–10<SUP>−4</SUP> mol/<I>l</I>) were obtained from the conductance kinetic runs by extrapolating conductances to time zero. The ionic equivalent conductances of the complex ions were 21.5–17.2 ohm<SUP>−1</SUP>cm<SUP>2</SUP>eq.-<SUP>−1</SUP>. and decreased with the increase of the chlorine content in the chloroacetato ligands. Little differences in the ionic equivalent conductances were observed between a pair of cis and trans isomers. The rate constants of the first order aquation of the complexes were estimated.
