ABSTRACT

Non-covalent interactions between of {N,N0-bis[(2-pyridinyl)methylene]-1, 2-benzenediamine]-bis (nitrato)}Cu(II) with pyridoxine hydrochloride in methanol were investigated by a combination of physico- chemical and spectrophotometric methods at T = (298.15, 308.15 and 318.15) K under ambient pressure. From measured density and viscosity data the apparent molar volume (/V), the slope (S V ), standard partial molar volume (/0 V ), standard transfer volume (Dt/0 V ), isobaric apparent molar expansibility (/E), standard isobaric partial molar expansibility (/0E ), the viscosity B-coefficient, its temperature derivative (oB/oT), solvation number (Sn) were calculated and discussed on the basis of specific or non-specific (solute + cosolute) and (solute + solvent) interactions. Thermodynamics of viscous flow were discussed on the basis of the transition state theory. Spectrophotometric results indicated 1:1 (solute + cosolute) interaction between the complex and pyridoxine hydrochloride.
