ABSTRACT

Limiting apparent molar volumes (/0 V ) and viscosity B-coefficients of iron(III)-N, N0-ethylenebis( 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: /0 V 1/4 a0 p a1T p a2T2, was used to determine the temperature dependence of the /0 V values; i.e., partial molar expansibilities (/0E ). The temperature dependence of partial molar expansibilities 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 FeIII(salen)Cl and the solvent mixtures. FeIII(salen)Cl was found to be a structure promoter in the ternary solutions.
