摘要：

We find that Gel substitutes cleanly for Al-III at the central tetrahedral site in the AlO4Al12(OH)(24)(OH2)(12)(7+) polyoxocation, creating a GeO4Al12(OH)(24)(OH2)(12)(9+) cation with some slight structural distortion, but a structure that overall still resembles an epsilon -Keggin molecule. These substituted aluminum polyoxo molecules are important because they resemble structural fragments at the surface of common aluminum (hydr)oxide minerals and can be used to study in detail the kinetics of oxygen exchanges with bulk solution.
