The cover picture shows the X‐ray structure of a six‐membered iron wheel. In order to support its existence in solution and to gain deeper insights into the possible flexibility of its scaffold, we prepared an indium analogue. Temperature‐dependent 1 H NMR solution spectra of the indium wheel (depicted in the middle) revealed intramolecular dynamics as exemplarily monitored for the diastereotopic benzylic methylene protons. Evidently the iron wheels are not only frozen beauties, but are also bubbly lively species. More details are given in the communication by R. W. Saalfrank et al. on p. 1899 ff.
