Limiting apparent molar volumes (phi(0)(v)) and viscosity B-coefficients of iron(III)-N, N'-ethylene-bis(salicylideneiminato)-chloride in binary mixtures of N, N-dimethylformamide (DMF) + acetonitrile (ACN) were determined from solution density and viscosity measurements at T = (298.15, 303.15, 308.15 and 313.15) K under ambient pressure. In the investigated temperature range, the relation: phi(0)(v) = a(0) + a(1)T + a(2)T(2), was used to determine the temperature dependence of the phi(0)(v) V values (partial derivative phi(0)(v)/partial derivative T)(p), i.e., partial molar expansibilities (phi(0)(E)). The temperature dependence of partial molar expansibilities (phi(0)(E)), i.e., (partial derivative phi(0)(E)/partial derivative T)(p) and viscosity B-coefficients were used to reveal the nature and degree of (solute + solvent) and (solvent + solvent) 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 results indicated strong (solute + solvent) interactions between Fe-III(salen)Cl and the solvent mixtures. Fe-III(salen)Cl was found to be a structure promoter in the ternary solutions.
