Ammonium metatungstate (AMT), a critical compound of the transition metal tungsten, features a core structure based on the Keggin-type polyacid anion [H₂W₁₂O₄₀]⁶⁻. This anion is formed by 12 WO₆ octahedra connected through corner- or edge-sharing, creating a cage-like structure typically centered by a heteroatom or proton. Stabilized by NH₄⁺ cations and crystal water molecules, this polyoxoanion forms a three-dimensional crystal structure. AMT’s crystal structure is generally monoclinic or triclinic, depending on crystallization conditions such as temperature, pH, and solvent. The crystal structure significantly influences AMT’s properties, including solubility, thermal stability, catalytic performance, and chemical stability. Below is a detailed analysis of these impacts.
