Abstract

The solubility, partial molar volume and standard integral molar enthalpy of solution of <i>cis</i>- and <i>trans</i>-[CoCl<sub>2</sub>(en)<sub>2</sub>]Cl in water, aqueous methanol, aqueous <i>tert</i>-butyl alcohol and aqueous acetonitrile are reported. The transfer functions ∆<i>G</i><sub>t</sub><sup>0</sup>, ∆<i>H</i><sub>t</sub><sup>0</sup> and <i>T</i>∆<i>S</i><sub>t</sub><sup>0</sup> as well as partial molar volumes are used to obtain information on the solute-solvent interactions. Results obtained are discussed in terms of differences in the surface charge distribution in isomeric coordination species. <p>
