Summary: | In this study partial molar volumes (φV0) and viscosity B-coefficients of
iron(III)-N, N'-ethylene-bis(salicylideneiminato)-chloride, abbreviated as
FeIII(salen)Cl, in different aqueous methanol solutions were determined from
solution density and viscosity measurements at temperatures 298.15, 303.15,
and 313.15 K under ambient pressure. Apparent molar volumes (φV) and
densities (ρ) were used to calculate the apparent molar expansibilities (φE),
the partial molar expansibilities (φE0) and the temperature dependence of the
partial molar expansibilities (φE0) at constant pressure, (δφE0/δT)P of
FeIII(salen)Cl solutions to reveal the nature of different interactions in
the ternary solutions. The transition state theory was applied to analyze the
viscosity B-coefficients on the basis of the activation parameters of viscous
flow. The overall results indicated strong solute-solvent interactions
between FeIII(salen)Cl and the solvent molecules, preferentially with water
molecules and that FeIII(salen)Cl acts as a net structure promoter in the
ternary solutions. UV-VIS absorption spectra of the ternary solutions also
stand in support of the results obtained. |
