Special on Polyoxometallates

The front cover of the Special Issue of the European Journal of Inorganic Chemistry Special on Polyoxometalates shows (top left) a snapshot of a simulated box of water containing [AlW₁₂O₄₀]^5- POM anions and their H₃O⁺ counterions, forming local aggregates (zoomed). Indeed, the free energy profile ΔG(d) calculated as a function of the POM···POM distance in water (top right) displays a minimum for the “contact” like-anion pair, corresponding to a high density of bridging counterions (inset, left). POMs also adsorb at the aqueous interface with graphite (bottom). The background is an extended view of the solution. Details are discussed in the article by G. Wipff and A. Chaumont on p. 1835ff.
