DOIAbstract
The reaction of the lacunary polyoxometalate precursor Na<sub>9</sub>[B-α-BiW<sub>9</sub>O<sub>33</sub>]·19.5H<sub>2</sub>O with Cu(II) ions was explored in search of new economic ways to copper tungstobismuthates as interesting prototypes for water oxidation and reduction catalysts. The emerging series of new 0D–3D polyoxometalate architectures with distinct copper cores was structurally characterized.
