The cover picture shows the structures of the mono‐ and diprotonated species of sulfamide, [H₂NSO₂NH₃]⁺ and [H₃NSO₂NH₃]²⁺, respectively. The isolation of salts containing these cations succeeded by the utilization of the superacidic systems HF/BF₃, XF/SbF₅ and XF/AsF₅ (X=H, D). In the background of the cover picture, a low‐temperature device for single‐crystal mounting loaded with a crystalline sample of [H₂NSO₂NH₃]⁺[BF₄]⁻ is shown. The structure analyses revealed remarkable changes, especially for the sulfur‐nitrogen bond lengths. More information can be found in the Full Paper by A. J. Kornath et al. on page 15825.

封面人物：用超强酸调节磺酰胺中的端基效应（Chem.Eur.J.59 / 2018）

封面图片分别显示了磺酰胺，[H ₂ NSO ₂ NH ₃ ] ⁺和[H ₃ NSO ₂ NH ₃ ] ²⁺的单和双质子化物质的结构。通过利用超酸性体系HF / BF ₃，XF / SbF ₅和XF / AsF ₅（X = H，D），成功分离了包含这些阳离子的盐。在封面图片的背景中，是一种用于单晶安装的低温设备，装有[H ₂ NSO ₂ NH ₃ ] ⁺ [BF ₄的晶体样品] ^-显示。结构分析显示出显着的变化，特别是对于硫氮键的长度。可以在A. J. Kornath等人的论文全文中找到更多信息。在15825页上。
