Abstract
Invited for this month's cover is the group of Andreas Kornath at the Ludwig-Maximilian University of Munich (Germany). The cover picture shows the crystal structures of protonated γ-butyrolactone ([(CH2 )3 OCOH][AsF6 ]) and γ-butyrolactam ([(CH2 )3 NHCOH][AsF6 ]). Both salts were synthesized by reacting the neutral compounds in the superacidic system HF/AsF5 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. Read the full text of their Full Paper at 10.1002/open.202000220.
