The Front Cover shows the crystal structures of protonated γ‐butyrolactone ([(CH₂)₃OCOH][AsF₆]) and γ‐butyrolactam ([(CH₂)₃NHCOH][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. More information can be found in the Full Paper by Stefanie Beck et al.

封面：γ-丁内酯和γ-丁内酰胺的质子化（ChemistryOpen 1/2021）

前封面显示了质子化的γ-丁内酯（[（CH ₂）₃ OCOH] [AsF ₆ ]）和γ-丁内酰胺（[（CH ₂）₃ NHCOH] [AsF ₆ ]）的晶体结构。两种盐都是通过使中性化合物在超酸性体系HF / AsF _5中在低温下反应而合成的。有趣的是，X射线结构分析不仅揭示了盐的结构参数，还揭示了两个物种中都存在C⋅⋅⋅F接触。进行量子化学计算以研究这些接触的性质。更多信息可以在Stefanie Beck等人的论文全文中找到。
