Preferred Abstract (Original):

Correlation with acceptor numbers was made for the solvatochromic behaviour ofbis-(2,2′-bipyridyl)-bis-cyanoiron(II) in binary aqueous mixtures of acetonitrile andDMF. The relationship between isosolvation point and donor number of the organic cosolvent was proved to be linear. Preferential solvation occurs by water in the case of the binary acetonitrile mixtures and byDMF in the case of the binaryDMF, aqueous mixtures.

Preferred Abstract (Original):

Preferential solvation ofbis-1,10-phenanthroline-bis-cyanoiron(II) was investigated in aqueous acetone and 2-methoxyethanol binary mixtures. The solvatochromic behaviour is discussed in terms of donor and acceptor numbers. The thermodynamic model ofFrankel was used to treat preferential solvation in the binary aqueous 2-methoxyethanol mixtures and reveals that preferential solvation by the organic solvent occurs. The preferential solvation constant at 298.15K was found to be equal to 3.30±0.039, and the free energy of preferential solvation amounts to 2.96kJ·mole−1.
