The cover picture shows the characteristic motif in the crystal structure of K[HS 2 O 7 ], which was obtained from reactions in SO 3 ‐rich oleum. Two crystallographically identical hydrogendisulfate anions [HS 2 O 7 ] – are linked into dimers via hydrogen bonds. This motif is retained if K + is replaced by Rb + , [NH 4 ] + , or even [NO] + cations. However, the crystal structure of Cs[HS 2 O 7 ] exhibits chains of hydrogen bonded [HS 2 O 7 ] – anions instead of the dimers as characteristic structural feature. The background of the picture shows single crystals of the potassium compound. More details are discussed in the article by L.V. Schindler et al. on page 2604ff.
