Abstract: | Solubilities in t-BuOH–, i-PrOH–, and EtOH–H2O mixtures at 298.2 K are reported for a number of salts of mono- and bi-nuclear cobalt(III) complexes. From these solubilities
and published single ion transfer chemical potentials, on the TATB (Ph4As +≡ BPh4-) assumption, transfer chemical potentials have been derived for most of these cobalt(III) complexes. The results and trends
are discussed in relation to those for other ions and complexes. Effects of ligand nature for transfer to t-BuOH–H2O mixtures are detailed and, for a selection of complexes, trends for transfer of a given complex to t-BuOH–, i-PrOH–, EtOH– , and MeOH– H2O mixtures are compared. |
