context_page_description: Keggin structure is the best known structural form for heteropoly acids. It is the structural form of α-Keggin anions, which have a general formula of [XM₁₂O₄₀]ⁿ⁻, where X is the heteroatom, M is the addenda atom, and O represents oxygen. The structure self-assembles in acidic aqueous solution and is the most stable structure of polyoxometalate catalysts.

It is the structural form of α-Keggin anions, which have a general formula of [XM₁₂O₄₀]ⁿ⁻, where X is the heteroatom (most commonly are P⁵⁺, Si⁴⁺, or B³⁺), M is the addenda atom (most common are molybdenum and tungsten), and O represents oxygen. The structure self-assembles in acidic aqueous solution and is the most stable structure of polyoxometalate catalysts.
