Cover Picture: Electronic Properties and Molecular Simulations of Polyoxometalates (Isr. J. Chem. 2/2011)

Abstract

Polyoxometalates (POMs) are molecular metal-oxide clusters that often feature highly symmetrical structures. A classical example is the Preyssler anion [NaP5W30O180]14− pictured on the cover. This D5h-symmetry cluster is presented as a ball-and-stick structure, with the tungsten atoms, W, in turquuoise, linked together by oxygen atoms in red, and the P atoms of its five encapsulated phosphate units in plum. The framework is surrounded by a set of points defining a surface, which serves to computationally simulate the effects of the solvent and counter ions. Further details can be found in the article by C. Bo and J. M. Poblet, on page 228 of this issue.
