Inside Cover: Solvent-Driven Reductive Activation of CO2 by Bismuth: Switching from Metalloformate Complexes to Oxalate Products (Angew. Chem. Int. Ed. 48/2016)

Bismuth is vaporized by a pulsed UV laser (background) to create a plasma containing Bi− anions, which are entrained into a supersonic expansion of CO2, producing [Bi(CO2)n]− clusters. In their Communication on page 15171 ff., J. M. Weber et al. show that small clusters have core ions based on BiCOO− metalloformate complexes (center). Solvation by an increasing number of CO2 molecules leads to a change in the core ion structure from metalloformate to oxalate (foreground). Cover picture: the Weber group and Steve Burrows, JILA.
