Müller A, Koop M, Bögge H, Schmidtmann M, Beugholt C. Exchanged ligands on the surface of a giant cluster: [(MoO3)(176)(H2O)(63)(CH3OH)(17)H-n]((32-n)-). CHEMICAL COMMUNICATIONS. 1998;(15):1501-1502.The synthesis of 1a.(32 - n)Na+.ca. 600 H2O.ca. 30 CH3OH 1 containing the ring-shaped, mixed-valence (Mo-V/Mo-VI) cluster [(MoO3)(176)(H2O)(63)(CH3OH)(17)H-n]((32 - n)-) 1a as a discrete unit in the crystal lattice is reported, which for the first time yields a compound of this type via a facile synthetic method and without amorphous reaction products; remarkably, H2O ligands can be replaced by CH3OH on the surface of a giant metal-oxide based cluster which has a nanometer sized cavity and, in contrast to zeolites, reducing properties
