The Front Cover shows the crystal structure of the salt of protonated ethylene carbonate [C 3 H 5 O 3 ][Sb 2 F 11 ]. Protonated ethylene carbonate was synthesized by reacting the neutral compound in the superacidic system HF/SbF 5 at low temperature. Interestingly, the single‐crystal X‐ray structure analysis revealed a planar CO 3 moiety with nearly equal CO bond lengths. Further theoretical investigations of the cation led to the result, that it contains a remarkably delocalized 6π‐electron system. On the cover this resonance stabilization is highlighted by p‐orbitals on the CO 3 moiety. More information can be found in the Research Article by Stefanie Beck et al.
