The Viscosities and molal volumes of <I>t</I>-butyl alcohol (<I>t</I>-BuOH) in aqueous solutions of [Fe(phen)<SUB>3</SUB>]Cl<SUB>2</SUB>, [Co(phen)<SUB>3</SUB>]Cl<SUB>3</SUB> (phen=1,10-phenanthroline), [Co(en)<SUB>3</SUB>]Cl<SUB>3</SUB> (en=ethylenediamine), tetraphenylphosphonium chloride ((C<SUB>6</SUB>H<SUB>5</SUB>)<SUB>4</SUB>PCl), tetramethylammonium chloride (Me<SUB>4</SUB>NCl), tetraethylammonium chloride (Et<SUB>4</SUB>NCl), and tetra-<I>n</I>-butylammonium bromide ((<I>n</I>-Bu)<SUB>4</SUB>NBr) were measured at 25 °C, and solute–solvent interactions characteristic of the metal chelate cations were investigated. The apparent molal volumes of <I>t</I>-BuOH in the solutions of [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP> are larger than those in the (<I>n</I>-Bu)<SUB>4</SUB>N<SUP>+</SUP> and [Co(phen)<SUB>3</SUB>]<SUP>3+</SUP> solutions. The hydrophobicity of [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP> is not so strong because of the aromaticity of the ligand. The same can be said for [Co(phen)<SUB>3</SUB>]<SUP>3+</SUP>. However, on the interaction between [Co(phen)<SUB>3</SUB>]<SUP>3+</SUP> and <I>t</I>-BuOH, the charge-dipole interaction and hydrophobic interaction act cooperatively to stabilize this pair through the overlap of the solvation spheres.
