Abstract
The enthalpies of dilution for aqueous solutions of [Co(en)3]Cl3, where en=1,2-diaminoethane, have been measured at 25°C, and up to m=1 mol-kg−1, using a new large isoperibol calorimeter by the “long-jump” method. Relative apparent molar enthalpies LФ have been extracted as an empirical equation relating LФ and m. Comparison with other 3∶1 and 1∶3 aqueous systems confirms the previously suggested hydrophobic character of the [Co(en)3]3+ cation.
