What is it about?
Polyoxometalates are molecular inorganic compounds capable of undergoing very remarkable processes. This review outlines, from a theoretical perspective, the redox behaviour of Keggin XW12O40 and Wells-Dawson X2W18O62 structures, and some derivatives of these. The effects of protonation, composition and isomeric forms are analysed to find connections with the observed and computed redox properties. Special attention is payed to the effect of electron delocalization on these phenomena.

Why is it important?
Several simple rules or trends are established to understand in the easiest way possible how polyoxometalates behave when redox processes occur. These straightforward take-home rules can help theoreticians and also experimentalists to draw plausible hypotheses on the behaviour of new complexes beforehand.
Perspectives
Putting together in a single article different aspects of polyoxometalate chemistry is a great opportunity for me to review and think again central aspects of this amazing area of chemistry which has been the focus of my research for the last 18 years. I would be grateful if this article helps polyoxometalate-science newcomers be interested in the field.
