The cover picture shows different views of the unprecedented molecular structure of the binary selenido mercurate anion [Hg 7 Se 10 ] 6– , which was obtained in a top‐down synthesis from the ternary selenido mercurate K 2 [Hg 2 Se 3 ] exhibiting a 3D structure. Treatment of the latter in the ionic liquid (C 4 C 1 Im)[BF 4 ] (C 4 C 1 Im = 1‐butyl‐3‐methylimidazolium) and small amounts of 1,2‐diaminoethane (en) at 80°C afforded the title compound (C 4 C 1 Im) 6 [Hg 7 Se 10 ] as light‐yellow single‐crystals. The structure was determined by X‐ray diffraction, and the Hg:Se ratio was confirmed by micro X‐ray fluorescence spectroscopy. More details can be found in the article by Carsten Donsbach, and Stefanie Dehnen on page 1383 ff .
