title: Self-assembly of a nanosized, saddle-shaped, solution-stable polyoxometalate anion built from pentagonal building blocks: [H34W119Se8Fe2O420]54-.
abstract: Precise control of the "one-pot" reaction conditions is employed for the assembly of a nanosized 2.8 nm cluster, [H(34)W(119)Se(8)Fe(2)O(420)](54-) (1a), which is templated using eight selenite units and two iron(III) centers. Not only is this cluster characterized structurally using X-ray crystallography, it is the largest polyoxotungstate to be observed intact in solution using ESI-MS, with a molecular mass of ca. 30,000 Da.
