Front Cover: High‐Pressure Synthesis and Single‐Crystal Structure Elucidation of the Indium Oxide‐Borate In 4 O 2 B 2 O 7 (Z. Anorg. Allg. Chem. 24/2017)

The Front Cover shows the indium oxide‐borate In 4 O 2 B 2 O 7 along the crystallographic c‐axis. This first representative of an oxide‐borate containing indium(III) is built up from bands of four, edge‐sharing InO 6 and InO 6+1 octahedra displayed in orange. These “orange bars”, formed by O 2‐ (blue) and In 3+ (yellow), are “stacked” alternatingly oriented in [1 1 0] and [110] – in the cover picture another of these elements is about to be added. Double‐tetrahedral B 2 O 7 units, shown in blue with centering B 3+ in red, interconnect the structure. As indicated by the “Score” achieved in this “Game”, In 4 O 2 B 2 O 7 is formed at 12.5 GPa and 1420 K using a Walker‐type multianvil apparatus. Details are discussed in the article by Hubert Huppertz et al. on page 2103 ff .
