EXCHANGED LIGANDS ON THE SURFACE OF A GIANT CLUSTER - [(MOO3)(176)(H2O)(63)(CH3OH)(17)H-N]((32-N)-)

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 lat tice is reported, which for the first time yields a compound of this t ype via a facile synthetic method and without amorphous reaction produ cts; remarkably, H2O ligands can be replaced by CH3OH on the surface o f a giant metal-oxide based cluster which has a nanometer sized cavity and, in contrast to zeolites, reducing properties.
