文摘
The high-nuclearity polyoxothiomolybdate [H8Mo84S48O188(H2O)12(CH3COO)24]32鈥?/sup> has been prepared and characterized by single-crystal X-ray crystallography and 1H NMR, IR, Raman, and UV鈥搗is spectroscopy. The solid-state structure reveals an unprecedented and intriguing arrangement consisting of a nanoscaled anionic cube. The surprisingly open structure of this {Mo84}-type cubic box features a large inner void that is accessible via its six open square faces with diameters of ca. 9 脜. Importantly, this molecular system appears to be highly functionalizable because of the presence of 24 exposed exchangeable acetate ligands.
