Synthesis of polyoxometalate clusters using carbohydrates as reducing agents leads to isomer-selection

Chem Commun (Camb). 2019 May 16;55(41):5797-5800. doi: 10.1039/c9cc02361e.


By using sugars as the reducing agents, we demonstrate that it is possible to control the self-assembly of polyoxomolybdates through selective preparation of a single heteropolyanion isomer. d-(-)-Fructose has been proved to be an effective reducing sugar compared to the chemically similar carbohydrate d-(+)-glucose. The gentle reduction results in favourable formation of the Wells-Dawson type gamma isomer in 6-fold reduced form at room temperature.
