Creation of bismuth-tungsten oxide nanoclusters using lacunary polyoxometalates.


Three types of heterometallic bismuth-tungsten oxide nanoclusters were successfully synthesized by the reactions of lacunary silicotungstates (trivacant [A-α-SiW9O34]10- and divacant [γ-SiW10O36]8-) and Bi3+ in organic solvents. Lone pairs on Bi3+ acted as structure-directing groups in these nanoclusters.
