2 O: MeOH mixtures at 40, 45, 50 and 55° C. The high negative ΔS* values found for the
complex cation under investigation, relative to that of trans-[Co (py) 4 Cl 2]+ reported in the
literature, were attributed to the substituent methyl groups. The free energies of transfer of
both the ground and the transition states were calculated from which the dominant effect of
the solvent on the transition state is apparent.
