Fate of a giant {Mo_(72)Fe_(30)}-type polyoxometalate cluster in an aqueous solution at higher temperature: Understanding related keplerate chemistry, from molecule to material

摘要

When the giant icosahedral {Mo_(72)Fe_(30)} cluster containing compound [Mo_(72)Fe_(30)O_(252)(CH _3COO)_(12){Mo_2O_7(H_2O)} _2{H_2Mo_2O_8(H_2O)}(H _2O)_(91)]·_(150)H_2O (1) is refluxed in water for 36 h, it results in the formation of nanoiron molybdate, Fe _2(MoO_4)_3, in the form of a yellow precipitate; this simple approach not only generates nanoferric molybdate at a moderate temperature but also helps to understand the stability of {Mo _(72)Fe_(30)} in terms of the linker-pentagon complementary relationship.
