The cover image shows the X‐ray crystallographic structure of a copper complex held by four hands.
The Front Cover shows the ultrahigh‐resolution X‐ray diffraction of a new CuI complex with the tripodal triphosphine ligand HTIM(PPh2)3, which has the shortest well‐described Cu···H–C bond so far [d(Cu–H) = 1.9 Å]. Both theoretical and experimental studies indicate a 3c–4e– anagostic interaction. The four hands under the X‐ray radiation symbolize the team effort toward discovering and characterizing the first example of this rare bonding situation, valuable for a better understanding of C–H activation intermediates. More information can be found in the Full Paper by J. Lloret‐Fillol et al. For more on the story behind the cover research, see the Cover Profile.
