Fate of a Giant {Mo₇₂Fe₃₀}‑Type Polyoxometalate Cluster in an Aqueous Solution at Higher Temperature: Understanding Related Keplerate Chemistry, from Molecule to Material

When the giant icosahedral {Mo₇₂Fe₃₀} cluster containing compound [Mo₇₂Fe₃₀O₂₅₂­(CH₃COO)₁₂­{Mo₂O₇­(H₂O)}₂­{H₂Mo₂O₈­(H₂O)}­(H₂O)₉₁]·150H₂O (1) is refluxed in water for 36 h, it results in the formation of nanoiron molybdate, Fe₂(MoO₄)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 {Mo₇₂Fe₃₀} in terms of the linker–pentagon complementary relationship.
