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 ([(CH ) OCOH][AsF ]) and γ-butyrolactam ([(CH ) NHCOH][AsF ]). Both salts were synthesized by reacting the neutral compounds in the superacidic system HF/AsF 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.
本月的封面邀请到了来自德国慕尼黑路德维希-马克西米利安大学的 Andreas Kornath 团队。该封面图片展示了质子化γ-丁内酯([(CH ) OCOH][AsF ])和γ-丁内酰胺([(CH ) NHCOH][AsF ])的晶体结构。这两种盐都是通过在低温下将中性化合物在超强酸性体系 HF/AsF 中反应合成得到的。有趣的是，X 射线结构分析不仅揭示了盐的结构参数，还揭示了两种物质中存在 C⋅⋅⋅F 接触。进行了量子化学计算以研究这些接触的本质。在 10.1002/open.202000220 上可以阅读他们全文论文的全文。
