Polyoxometalates (POMs) are complex ions composed of metals and oxygen atoms which exhibit unique electrochemical properties. In this study, the redox properties of a europium-bridged polytungstate, Eu(P2W17O61)217-, were observed in the presence of different cations. A phenomenon previously seen in single atom bridged POMs was observed in this complex as well. Additionally, the effect of concentration of POM on the peak potential of the last reoxidation peak is presented. Finally, the effect of the presence of Al3+ on the cyclic voltammogram of the complex ion is shown.
