Abstract

We find that Ge^IV substitutes cleanly for Al^III at the central tetrahedral site in the AlO₄Al₁₂(OH)₂₄ (OH₂)₁₂⁷⁺ polyoxocation, creating a GeO₄Al₁₂(OH)₂₄ (OH₂)₁₂⁸⁺ cation with some slight structural distortion, but a structure that overall still resembles an ε-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.
