Abstract

The microscopic ionic volumes, v _A, of complex inorganic anions, obtained from crystal unit cell volumes, as well as their standard molar volumes, $$ V-{\text{A}}^{\infty } $$ V A ∞, in aqueous solutions serve to establish whether these anions are water-structure-breakers or -makers. This is done via correlations with well known criteria for such effects, namely the ionic viscosity B-coefficients and the structural entropies. Complex anions with charges z _A are structure-breakers if v _A > 0.1|z _A| nm³·ion^-1 or $$ V-{\text{A}}^{\infty } $$ V A ∞ > 35|z _A|^4/3 cm³·mol^-1 and structure-makers if otherwise.
