Abstract
The solvatochromism observed for substituted cyanoiron complexes depends on the acceptor properties of the solvents, according to v = vo + a(AN), where ν is the measured spectral charge transfer energy and AN refers to the acceptor number scale. The parameter a was found to be strongly influenced by the solvation characteristics of the ligands compared with those of the cyanides. In H2O+S mixed solvents, preferential solvation by water was observed where S was acetone or acetonitrile, but not when S was methanol, dimethylsulfoxide, dimethylformamide or related solvents.
