Front Cover: Cation-Directed Isomerization of the U28 Uranyl-Peroxide Cluster (Eur. J. Inorg. Chem. /2017)

The Front Cover shows an artistic representation of the outer surface of a nanoscale U₂₈ cage cluster. Three uranyl moieties connected by phosphonic bridges (μ₃-HPO₃) can be seen in the image, which depicts μ₃-HPO₃ conformations with and without an associated cation directly inside the cage. ¹H NMR spectroscopy provides a direct way to monitor this conformational change as cations like sodium are introduced into the solution. Yellow, red, green, white, and purple spheres represent uranium, oxygen, phosphorus, hydrogen, and sodium, respectively. (Artist: Dr. Anna F. Oliveri). More information can be found in the Communication by A. F. Oliveri et al. For more on the story behind the cover research, see the Cover Profile.
