  "abstract": "We report on the synthesis and structural characterization of the polyoxo-20-molybdate wheel, [MoVI₂₀O₆₀{AsO₂(CH₃)₂}₁₂]¹²⁻ (Mo20), which can be isolated with an empty cavity (diameter ca. 2 nm) or containing two dimethylarsinate guests, depending on the type of cations used during synthesis. The polyanion Mo20 was characterized by single-crystal XRD, FT-IR, and TGA, and in solution by multinuclear NMR (¹H, ¹³C, ⁹⁵Mo) and ¹H DOSY, as well as x-ray scattering (SWAXS) and mass spectrometry (ESI-MS). We demonstrated a fast, quantitative, and fully reversible transformation of Mo20 to [MoVI₄O₁₂(OH){AsO₂(CH₃)₂}]²⁻ (Mo4) in aqueous solution, whereas Mo20 is cleanly and quantitatively recrystallized from such solution, indicating a unique phenomenon, which is fully supported by all experimental techniques used as well as DFT and MD calculations.",
