The conductance of tris(1,10-phenanthroline)iron(II) sulfate, Fe(phen)<SUB>3</SUB>SO<SUB>4</SUB>, and chloride, Fe(phen)<SUB>3</SUB>Cl<SUB>2</SUB>, has been measured in water-methanol mixed solvent at 25 °C. The data of the sulfate could be explained by means of the Fuoss-Onsager equation (1957) and the Fuoss-Onsager-Skinner equation (1965) on the assumption that the salt is completely dissociated in the entire composition range of the solvent system. Application of the Fuoss-Hsia equation which contains a <I>c</I><SUP>3⁄2</SUP> term gave association constants increasing from a value of <I>K</I><SUB>A</SUB>=40 in water to <I>K</I><SUB>A</SUB>=3900 in methanol. The log<I>K</I><SUB>A</SUB> <I>vs</I>. 1/<I>D</I> plot is in good agreement with ion association theoreies. The limiting equivalent conductance of Fe(phen)<SUB>3</SUB><SUP>2+</SUP> ion was estimated to be 34.3 in water and 62.3 in methanol.
