The Front Cover shows the crystal structures of protonated γ‐butyrolactone ([(CH 2 ) 3 OCOH][AsF 6 ]) and γ‐butyrolactam ([(CH 2 ) 3 NHCOH][AsF 6 ]). Both salts were synthesized by reacting the neutral compounds in the superacidic system HF/AsF 5 at low temperature. Interestingly, the X‐ray structure analyses revealed not only structural parameters of the salts, but also the existent of C⋅⋅⋅F contacts in both species. Quantum chemical calculations were performed to investigate the nature of these contacts. More information can be found in the Full Paper by Stefanie Beck et al.
