Abstract

The largest inorganic molecular system so far, [(MoO<sub>3</sub> )<sub>176</sub> (H<sub>2</sub> O)<sub>80</sub> H<sub>32</sub> ] (1; the picture on the right shows the polyhedral representation), which has been characterized by X-ray structure analysis, possesses a cavity of diameter 2.3 nm and remarkably shows the stoichiometry of a (reduced) protonated and hydrated "molecular molybdenum trioxide". It is formed by reduction of an aqueous solution of lithium molybdate with tin(II) chloride at very high H<sup>+</sup> concentrations.
