Abstract

The aqueous coordination chemistry of Al³⁺ and Fe³⁺ is compared. The differences in electronegativities (X_m ), ionic radii (r_i ) and electron configuration (dⁿ ) for the two ions are shown to influence trends in aquo ion structure and reactivity, hydrolysis, and metal complex stability. Similarities in coordination chemistry result in similarities in distribution and modes of transport for Al³⁺ and Fe³⁺ in a biological system.
