Crystallography and molecular interactions

Abstract The cover picture shows the molecular structure of the neutral mononuclear iridium complex Cp*Ir(η 6 ‐C 6 H 2 O 4 )(BF 2 ) 2 exhibiting an anion–π interaction between CF 3 SO 3 and metallated pentamethylcyclopentadienyl “η‐Cp*Ir”. Computational analysis (see optimized structure) shows that this type of noncovalent interaction can be better described as a combination of anion–π and CH···anion hydrogen‐bonding interactions. Both contributions work in harmony. Details are discussed in the Short Communication by H. Amouri et al. on p. 3703 ff. The background depicts the famous réverbère “street lamp” of Paris, which resembles the iridium complex holding the anion. The lamp shown in the image is located on Île Saint‐Louis, often considered the most romantic part of Paris. The cover picture was designed by H. Amouri.
