“…Values for transfer from water are included in Table 2. The transfer chemical potential trends for cisplatin and carboplatin are shown in Figure 1, where they are compared with the few trends available for other platinum(II) and palladium(II) complexes (Blandamer et al 1981, Burgess & Abu-Gharib 1984 Figure 2. There is a range of solvation preference, from a marked [;reference for water for the upper complexes in Figure 2 to a significant preference for methanol for the bottom two complexes.…”

“…Transfer chemical potentials have been reported for a number of inorganic complexes to methanol + water mixtures, including a number of low-spin iron(II) [12,13], iron(III) [13,14], platinum(II) [15], chromium(III) [13,16] and cobalt(III) complexes [16][17][18][19][20][21][22][23][24]. The cobalt complexes range from [Co(NH 3 ) 6 ] 3+ [17,18] through simple ternary complexes such as [Co(NH 3 ) 5 Br] 2+ [19], [Co(NH 3 ) 5 (NCS)] 2+ [20], [Co(NH 3 ) 4 (SO 4 )] + [21], and several thiocarboxylate complexes, e.g.…”

Solubilities in MeOH-H 2 O 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 TPTB (Ph 4 P + ¼ BPh À 4 ) assumption, transfer chemical potentials have been derived for these mono-and bi-nuclear cobalt(III) complexes. The results and trends are discussed in relation to those for other complexes and ions in these binary aqueous solvent mixtures.

Rate constants for base hydrolysis of the trzs-( 1,lO-phenanthroline)iron(II) cation and for solvolysis of the cis-dichlorobis(l,2-ethanediamine)cobalt(III~ cation have been measured in binary aqueous mixtures containing l,a-ethanediol, 1,2-or 1,4-butanediol, 1,2-or 1,6-hexanediol, 1-propanol, or t-butyl alcohol, at 298.2 K. Kinetics of base hydrolysis of the cobalt(II1) complex have also been monitored in methanol-water and ethanol-water mixtures, again at 298.2 K. The observed reactivity trends are discussed in terms of the hydrophilic and hydrophobic properties of the respective diols. The dominant factor determining reactivity is hydration of the attacking hydroxide or leaving chloride, as is evidenced by the close correspondence between rate constants and transfer chemical potentials for these anions. The role of hydration has also been probed through the determination of activation volumes for these two reactions in 60% 1,4-butanediol.
