The high-nuclearity polyoxothiomolybdate H (8) Mo (84) S (48) O (188) (H (2) O) (12) (CH (3) COO) (24) (32-) has been prepared and characterized by single-crystal X-ray crystallography and (1) H NMR, IR, Raman, and UV-vis spectroscopy. The solid-state structure reveals an unprecedented and intriguing arrangement consisting of a nanoscaled anionic cube. The surprisingly open structure of this Mo (84) -type cubic box features a large inner void that is accessible via its six open square faces with diameters of ca. 9 Å. Importantly, this molecular system appears to be highly functionalizable because of the presence of 24 exposed exchangeable acetate ligands.
