Invited for this month's cover picture is the group of Prof. Andreas J. Kornath at the LMU in Munich (Germany). The cover picture 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. Read the full text of their Research Article at 10.1002/open.202100229.
